On the Cover...We Care … for Oz
South Africa is a beautiful country in the southern hemisphere that off ers
a world of treasures. The fi rst thing that comes to mind when we think of Africa is wildlife.
The big fi ve, elephant, rhino, buff alo, lion and leopard are animals we visualize. Strong and dominant but unfortunately also fragile to men. The largest population of rhinos lives in South Africa. This beautiful animal that has wondered the earth for 50 million years is now endangered. Illegal poaching has reached its peak and has become an industry.
Prior to 2006 rhino poaching was maintained, but since then skyrocketed. If the killing of rhinos continues at this rate, death will overtake birth within the next two to three years. We cannot be responsible for the extinction of one of the great treasures of Africa. It is time to step up!
CARE for WILD AFRICA represents the tremendous eff orts of Petronel Nieuwoudt, a lady with more than 20 years of experience in the care and conservation of wildlife. She has now consolidated her eff orts to develop a center in South Africa devoted to the care and rehabilitation of African wildlife.
Care, hand rearing management and capture of infant, injured/orphaned animals are the passions that drive CARE for WILD AFRICA. Petronel is also one of a few who has specialized in the care of orphaned and injured rhinos.
For Pepperl+Fuchs it all started when Dr. Kegel, CEO of Pepperl+Fuchs Germany came to South Africa for the Pepperl+Fuchs Offi ce inauguration in Johannesburg. During this visit, he became aware of the poaching problem
in South Africa. Hearing about this, he left determined to get the company involved in the cause to save the rhinos. When Marc Van Pelt, Managing Director of Pepperl+Fuchs in South Africa, communicated the story of a baby rhino found in the Kruger National Park to Dr. Kegel, the company got the opportunity to assist.
The baby rhino’s mother was poached near Lower Sabie, he was about 4 months old. He was a very shy calf as he witnessed his mother being killed with a rifl e. This story came to the attention of one of the private shareholders of Pepperl+Fuchs and the decision was made to adopt “Oz”, (8 months old & 255kg today) at the ‘CARE for WILD AFRICA’ Rhino Sanctuary.
Pepperl+Fuchs is at home on every continent. Automation is our world. Perfect application solutions are our goal. Founded in 1945 as a radio repair shop,

Efficiency and availability of production facilities depend
on the reliable transmission of signals between field devices and the process controller. Interference in the signal circuit may cause related processes to run incorrectly. It is the task of the galvanic isolation function on signal conditioners to prevent this problem. These conditioners may offer additional functions such as signal splitting or signal conversion.
However, users are not interested in having a multitude of functions, but having a product design that meets their requirements.
Ensuring safe and efficient process control is a must when it comes to initiating a seamless workflow with a high degree of production stability. This process control is closely linked with error-free transmission of measurement and control data between the sensors in the field and the control level, or between the controller and the actuators. Interference in the signal path between the field and control level can cause processes to be controlled incorrectly due to distorted signals.
One potential cause for interference of this kind is the equalizing currents created as a result of ground loops. These currents are caused by differences in potential between the grounded field and controller sides. They lead to deviating measuring and controller signals and can affect communication to such an extent that safe process control is no longer an option. Similar problems occur when high-performance components
Signal conditioning - what is it?
are grounded near signal lines or cause interfering signals from frequency converters in motor load changes.
Interference can be fed directly into the signal path as well. Sensors are often installed in pumps, motors, and fans to monitor temperatures, frequencies, or oscillations. If an isolation problem occurs on these devices, high voltages can find their way into the measuring circuit and cause a surge on the signal line. If the total of the signal current and fault current is between 4 mA and 20 mA, the fault will not be detected and displayed as a malfunction, but can still have serious consequences.
Signal conditioners are used exclusively in safe areas. They do not have a barrier function designed to prevent unacceptably high energy in hazardous areas.
The use of signal conditioners is particularly helpful if:• plants are large and have long
signal paths.• Powerful components are
grounded in the vicinity of the signal lines.
• The signal line environment is placed under significant electromagnetic charge by other signals or by motors with frequency converters.
• No single-channel input isolators are present in the respective controllers.
Signal conditioning is more than galvanic isolation
Galvanic isolation as offered by signal conditioners can prevent interference of this kind, or at the very least protect the process control system. The signal conditioner separates the
loop into two circuits, which are connected to each other via a transformer.
Other tasks performed by these interface modules include converting signals. Conversion is needed if field devices cannot deliver the standard signals that the controller needs to process the signal.
This situation exists with many small PLCs. Even though they are cost-effective, they often have only voltage inputs as standard. This is why a signal transformer is needed if only current signals are provided from the field. In addition, the analog inputs are usually purely passive—a transmitter power supply with current output or voltage output via a signal conditioner is therefore very beneficial. Also, small PLCs often allow only a few signal types on the input side. You will generally not find temperature inputs for all commercially available temperature sensors.
Signal conditioners offer short-circuit protection for each individual current circuit, since the conditions switch corresponding outputs on the control side into the safe mode. Measuring instruments on other channels are not affected by a failure.
Often, field signals need to be shared by various systems, such as control systems, emergency shutdown (ESD) systems, or data acquisition systems. If this is the case, several systems must not be connected in series to the output side. If the connection to one of the systems were to be interrupted, none of the other systems would receive any more signals either. The galvanically isolated outputs on a signal splitter guarantee reliable distribution of the process signals to the various systems.
This avoids the problem of high resistive loads in a series connection.
Eliminating counter currents plays a role when viewed against safety and availability. If field devices such as 4-wire transmitters with active current output and a control system attempt to supply current to the signal circuit, the result is a nonfunctioning current circuit. With signal conditioners,
it is usually possible to handle all combinations of current sinks and current/voltage sources.Safety First—Isolation Quality
The basic functions of signal conditioners have varying technical differences, depending on the supplier.
The main customer need is good isolation, to ensure the device reliably fulfils its core tasks. The isolation quality of a circuit is influenced by many parameters. Influencing factors range from circuit design, such as the spacing between the isolation plugs, to the quality of components used. The need for electric strength increases proportionally, since users increasingly face high, steep pulses. The test voltages and maximum permissible working voltages are relevant in this regard; today they are typically anything up to 3 KV (test voltage) or 300 V (working voltage) and thereby ensure protection against contact on the controller side.
A crucial factor for users when choosing devices is often whether the manufacturer has much experience in developing and manufacturing isolated barriers for hazardous areas. After all, it is precisely in the hazardous area that good isolation quality is essential; the products used here must meet stringent standards as well as passing various external tests. For logistical reasons, the higher-value circuit concepts and components for the isolated barriers for signal conditioners are then applied, ensuring that users receive extremely reliable products.Every Degree Counts
When selecting signal conditioners, it is important to look for low self-heating and a relatively high permissible operating temperature—for switch cabinet builders, literally every degree counts. Today’s standard operates at an ambient temperature of up to 70 °C. However, the requirements for the lower temperature limit are by no means unlimited. Ambient temperatures lower than - 20 °C are not practical in switch cabinets. The Measure of All Things
According to users, suppliers often underestimate the importance of the dimensions

and mechanical properties of isolators. A module width of as little as 6 mm is possible today and is offered by various companies—even for dual-channel types with a packing density of 3 mm/channel. However, the overall height is also a big factor to consider. Experience has shown that in virtually pure signal conditioner applications—i.e., without or with a small number of isolated barriers—you can find products from multiple suppliers. When replacing or expanding, new signal conditioners must fit into the existing switch cabinet grid. From the users’ perspective, noncritical functions such as the display or removable terminals are actually counterproductive
when viewed against this background—both functions require extra space.
The mechanical stability of the housing is important in the context of mounting and handling—something that manufacturers often underestimate but is repeatedly requested by customers. With this in mind, Pepperl+Fuchs carries out Elmech tests in a separate, independent testing laboratory. The purpose of these tests is to examine the mechanical properties of the devices according to the specified standards. The tests include subjecting prematurely aged devices to mechanical and climatic loads and then
monitoring compliance with the relevant specification.
The use of signal conditioners in safe areas effectively prevents interference in the signal path between the field and control level, thereby increasing machine and plant availability. Interference of this kind may be undetected equalizing currents, but could equally be dangerous contact voltages in specific fault situations on the field side. Signal lines in large plants or near grounded, powerful devices are particularly sensitive to interference. The increasing electromagnetic load of plants and the related risk of unwanted couplings can be effectively counteracted with galvanic isolation provided by
signal conditioners. Furthermore, signal conditioners offer key additional functions such as signal splitting or signal conversion. The latter is increasingly gaining importance in areas where there are larger numbers of small PLCS that can process only a limited range of input signals. In addition to the basic functions, users want signal conditioners that are practical and technical in design: first-class isolation quality, maximum permissible ambient temperature, minimum height and width of the module, and robust mechanisms can all be found at the top of users’ wish lists.

Galvanic isolation prevents equalizing currents in ground loops and also protects controllers against other interference
If galvanic isolation is not present, an equalizing current can flow via the grounding shared by field devices and the controller; it is this current that distorts the signal current

The CSI 6500 ATG protection system is a stand-alone machinery protection solution
that also allows users to cost-eff ectively introduce prediction monitoring of critical assets from the same system. Predictive intelligence is a key component to increasing availability and improving the reliability of plant assets.
Embedding prediction data into protection system to improve reliability of critical assets
New CSI 6500 ATG multi-functional cards can be easily reconfi gured for a wide range of measurements, including the impacting or peak-to-peak data used in the unique PeakVue™ technology. In addition to monitoring the start-up and coast down of critical turbo machinery for safe operation, users will be able to utilize PeakVue technology to identify the earliest indications of developing faults in gearboxes and bearings.
With the CSI 6500 ATG, it is no longer necessary to return to the control room or open cabinets in the fi eld to view or analyze data. The CSI 6500 ATG can be networked over wired or wireless Ethernet to deliver asset health information to authorized users through a PC or phone application.
To facilitate easy system integration
with third party systems, CSI 6500 ATG is the fi rst protection system to include a secure embedded OPC UA server.
Studies show that it costs 50% more to repair a machine after it has failed versus predicting the failure and thus planning for the repair costs. For users whose budget doesn’t cover the cost of both a protection and a prediction system, getting prediction data from a protection system is an incremental step towards improving the insight on asset health.
The CSI ATG system complies with the traditional API 670 certifi cation and is certifi ed for installation in demanding environments where Class 1 Div2/ATEX Zone 2 approvals are required.
In keeping with the Uno Power power supply range, the UnoUPS uninterruptible power supply is now available with a 60 W output power and integrated power storage in a compact housing.
The UPS operates fl exibly at input voltages of 23 to 30 V DC. The integrated lead AGM power storage ensures long buff er times of 45 minutes at 0.5 A, for example. When combined with a Uno Power power supply from the 100 W performance class, the overall dimensions are just 160 x 90 x 90 mm. This means that this space-saving APS is also suitable for small control and distributor boxes.
The high MTBF (mean time between failure) value of over 1.9 million hours and the large temperature range of -15 to +50°C are superb features for a device of this performance class. The device also has LED status indicators for signaling and function monitoring, as well as active 24 V DC switch outputs for forwarding to a higher-level control system.
Compact UPS with integrated power storage
Demand-oriented motor control is enabling users to reduce their electricity
consumption by up to 80% compared to fi xed-displacement drives. Bosch Rexroth has recently added two new models to its range of frequency converters, the EFC 3610 and EFC 5610, to provide intelligent speed and torque control for motors from 400 W up to 18.5 kW.
Bosch Rexroth’s EFC-class frequency converters are open-source, scalable and expandable drive controls that are easily integrated into many diff erent kinds of
Frequency converters enabling leaner automationmachines and automation environments, including in pumps, compressors, fans, conveyors, presses and packaging machines.
The EFC 3610 is a universal, low-cost converter for control and demand-oriented energy supply for almost all industry segments. The EFC 5610 is a high-torque solution with effi cient, high-performance vector control for specialised requirements and an expanded power range (up to 18.5 kW). Both are available in heavy-duty and normal-duty confi gurations.
The communications interface of the EFC converters has expanded to include support for Modbus, Profi bus and CAN bus protocols. Pluggable I/O connection terminals and fi eldbus modules enable a high degree of expandability and fl exibility in the way drive architectures can be confi gured. Integrated brake choppers and mains fi lters (EN61800-3 C3) reduce the need for external componentry, enhancing the plug-and-play functionality of these products. Process control is improved
through integrated PID controllers alongside an eight-step sequence control system.
Other innovative features, such as the detachable control interface that allows parameters to be dumped into additional drives using the panel’s memory and copy function, enhance the overall usability of the EFCs. Additional braking resistors are available for applications where the controlled motor is required to stop instantly, dissipating the electromotive voltage.
The Bosch Rexroth frequency converter range will soon be expanded to support motors up to 22 kW, and will also include the Ethernet range of communications.
Apart from lowering the electricity bill through reduced and more effi cient consumption, frequency converters lower capex by reducing the requirements of the associated switchgear, while also limiting component stress for a longer motor life.

The ARCA angle style control valves Series 350 and 380 are proven under critical process conditions for a long time. If used in steam
or process gas applications at high pressure and temperature, in cavitation-free relaxation of liquids at high pressure diff erential or in handling of forces fl uids with high solid contents; the modular system of valve housings, bonnet and trim styles, in combination with a large range of materials, always off er an ideal solution.
The combination of high pressure ratio and solid-containing fl uids is one of the most critical challenges for sizing, selection and design of a control valve.
Due to the high pressure ration multi-stage valves indispensable to avoid severe cavitation damages; however as soon as the fl uid contains solid particles besides the normal fl uid-dynamic sizing (determination
Multi-stage trim for blowdown of fl uids containing solid matters
of the number of throttling stages and their individual fl ow coeffi cient), the grain size of the particles has to be taken into account. The cross-section area of each fl ow channel in the valve must be that size and shape, which allow all particles in the fl uid (assumed to be of spherical shape) to pass.
Since the cross section area if each throttling stage is explicit defi ned by the fl ow coeffi cient calculated form the fl uid-dynamic valve sizing, only the shape of the fl ow channel remains to optimize.
It is obvious, that a circular shape is the optimum with regard to the permeability of spherical particles. The new-developed multistage trim MS4, which has only one fl ow channel each stage, milled as a spherical calotte into a rigid, multiple guided control rod, approximates this ideal shape in ideally way and is superior to any multistage parabolic plug in this point of view.
Another special feature of this trim style is the protection of the seating surface (which is the most sensible area in terms of erosion) by overstroke of the valve. With this, the control stages of the valve will open only as soon as a low pressure diff erential and with this a low small fl ow velocity at the seating surface is maintained.
The rigid multiple guidance of the control rod is an eff ective prevention of the valve against mechanical vibrations and the resulting wear, even at extremely high pressure diff erentials.
Series 350 and 380 are available in sizes up to 10” (DN 250) and ratings up to Class 2500 (PN 400). Depending on the process conditions, MS4 trims can be delivered in valve sizes up to 4” (DN 100).

Since 1988 the 5700 range of Fluke calibrators, has set
the standard for multifunction calibrator performance in calibration laboratories worldwide. Fluke has now introduced what they are calling the “gold standard” of multifunction calibration – the very impressive 5730A high performance multifunction calibrator.Features:• Improved performance
specifications for ac voltage, ac current and resistance
• 6.5 inch CGA capacitive touch screen with full colour graphical user interface
• Visual Connection Management™ terminals guide cable connections
• Compatible with 52120A and 5725 amplifiers
• Full MET/CAT® compatibility with 5700A and 5720A procedures
• Artifact Calibration using 10V, 1Ω and 10kΩ external standards
Like its predecessors, the 5730A calibrates a wide range of digital multimeters, up to long-scale 8.5 digit DMM’s as well as RF voltmeters when equipped with the wide band option. But this new model features improved specifications that will help users increase test uncertainty ratios (TURs) and increase test confidence. Also, the improved specifications will reduce the need to guardband, giving users confidence and peace-of-mind with calibrations.
The 5730A is designed for calibration professionals who require the most accurate dc/lf signals available in a multifunction calibrator. Metrologists in national laboratories, the military, third
New Gold Standard in electrical calibration
party calibration laboratories, and corporate users with high-end workload value the performance and reliability of the 5730A. All 5730A calibrators are traceable to international standards and are produced in the factory with ISO/IEC 17025 accredited calibrations.
Specifications are stated to the standard Fluke Calibration 99% confidence level (as well as 95% confidence level) to support easy measurement comparisons, according to international quality standards. Specifications are absolute and include the uncertainty of the calibration standards used. No additional analysis is required.
The 5730A calibrator incorporates the latest technology, such as surface mount technology and modern digital components, that have enabled Fluke Calibration to advance the proven design of the 5700A/5720A and create the next generation of high performance multifunction calibrators.
The 5730A keeps many of the front-panel details that characterize its predecessors, while adding a new full color touch screen display to enhance usability and ease calibration. Users enter values via a familiar, calculator-style keyboard, working naturally from left to right. A new graphical user interface features easy-to-read, easy-to-use menus, as well as access to common functions. Status indicators for OPERATE, STANDBY, and HAZARDOUS VOLTAGE appear on the screen in bright letters or icons - easily recognizable – even from across the calibration lab. The redesigned front panel features many new improvements, like Visual Connection Management™
output terminals that light up to show which terminals are active, guiding the user to make the correct connections. The handles and knob are overmolded for comfort and feel. USB ports are placed both on the front and rear of the unit. Use the port at the front to download internal calibration constants; use the rear port for remote communication with a PC—or choose the LAN, IEEE or serial interfaces.
The 5730A calibrator features Artifact Calibration. Only three artifact standards—a 10 V dc reference and 1 ohm and 10 k ohm resistance references—are required to calibrate all ranges and functions to full specifications. Front panel GUI instructions prompt the operator tomake connections and inputs each step of the way. The calibrator controls the process, which takes only about an hour, compared to several hours using traditional calibration methods. In addition to saving time and equipment costs, Artifact Calibration can extend time between calibrations of the 5730A to two years before a full verification check by a Fluke Service Center is required. And, because the 5730A can tolerate operating temperatures between 15 °C and 35 °C, it can be calibrated where it’s used, rather than having to be shipped to a standards laboratory for calibration. Artifact Calibration
When Artifact Calibration was first introduced in the Fluke 5700A, customers asked many questions about traceability because they were surprised that one could calibrate so many ranges and functions with only three external standards.
However, thanks in part to considerable testing and evaluation by three national laboratories in Europe, Artifact Calibration is fully validated by the metrology community. Today many metrologists rely on Artifact Calibration to maintain their Fluke calibrators at 90-day specifications for up to two years. Significant savings can be realized in calibration costs by only performing a full verification at a certified Fluke Service Center every two years. The time savings are also significant, as Artifact
Calibration allows the 5730A to remain in service and conducting calibrations when it would otherwise be unavailable due to shipping and service time.
Cal CheckFor extra confidence that
the 5730A calibrator stays within its specifications between calibrations, the built-in automated Cal Check function checks every range and function against a set of dedicated internal standards to monitor the drift of each.
These Cal Check results can be downloaded to a computer via the USB port conveniently placed on the front of the unit to develop control charts predicting the calibrator’s long-term performance. It may be surprising to learn that the internal standards built into every 5730A are the functional and design equivalents of a Fluke 732B 10 V reference plus two fully characterized metrology-grade resistance standards. These standards—totally separated from the output circuitry—are not used in normal operation and are provided solely to provide a check. Improving calibration
The most prevalent long-scale digital multimeters in the world are the Fluke Calibration 8508A and the Agilent 3458A. Due to the high level of accuracy of these two 8.5 digit DMMs, there are several points where calibration professionals are forced to use a technique known as guardbanding. This method decreases the measurement uncertainty for a particular value in order to guarantee the calibrated value falls within the appropriate 99% or 95% confidence interval. In designing the new 5730A, Fluke Calibration worked diligently to bring users even better performance specifications to help address some of these “problem points.” High current output to 120 A
Paired with a Fluke Calibration 52120A Transconductance Amplifier, the 5730A can output up to 120 A, and display the output on the 5730A touch screen display. Operating in closed-loop mode with the 52120A, the 5730A maintains the best current accuracy over the widest range of calibration workload. The new
18.6

5730A is also compatible with the Fluke Calibration 5725A Boost Amplifier. Guardbanding
As mentioned earlier, it has been become increasingly difficult to always meet the industry recognized test uncertainty ratio (TUR) of 4:1. To minimize the chance of approving an out-of-tolerance (OOT) condition during calibration, the practice of guardbanding is employed. As all measurements are subject to error, most measurements assume a normal distribution commonly referred to as a “bell curve.” When the TUR is less than 4:1, the error band of the unit under test (UUT) is small enough that the calibrator cannot guarantee that the measurement is within specification.
In Figure 1, the uncertainty bell curve is shown at the upper specification limit of a UUT.
There is a 50 percent chance that the measurement is OOT, and 50 percent that it is in tolerance.
To protect the metrologist, guardbanding moves the specification limit closer to the nominal value in order to “guard” against the possibility of approving an OOT condition.
As shown in Figure 1, the measured value must now fall within a smaller offset from the nominal value, providing 95 percent confidence that the actual value is within the new specified band. This gives the metrologist the confidence that the measurement is accurate. The new 5730A calibrator is the most accurate dc/lf calibrator available, but it still requires the use of guardbanding for the most demanding long-scale multimeters.

The MDM25 is a new portable relative humidity hygrometer which replaces
model DM509. The device is a hand held, battery-operated meter and is available with fi ve diff erent types of probes. The MDM25 is ideal for several testing and inspection applications as it shows temperature as well as relative humidity values.
The highly stable sensor, based on polymer present in the device, quickly responds to the changes sensed in humidity and a thermistor measures the optimum temperature. Additional derived parameters from humidity and temperature include dew point, wet bulb temperature and absolute humidity.
The MDM25 hygrometer can be used as a reference device that is used with humidity
New relative humidity hygrometergenerators during a RH probes validation or calibration. RH probes are widely used by pharmaceutical companies, laboratories, and manufacturers of semiconductors.
A secondary reference is used while calibrating together with a humidity generator, like the Michell S503.
The MDM25’s display orientation can be inverted and can easily be read when the fi xed probe is inserted into the S503. The MDM25 facilitates ease of use in varied circumstances and applications and the range of probes available include a fi xed probe, a sword probe, and round hand held probes up a length of 500mm.
N Series relays are designed for simplicity without compromising reliability. The relays off er coordinated tripping on potentially high-energy faults ensuring that the main contactor is not used to clear such faults. A duplication of trip and fault annunciating N.O contacts provides control rooms with a hard-wire solution for information and reset possibilities.
The relays are housed in a versatile enclosure which caters for door mount, chassis mount or C.T. module mounting. Protection features include selectable thermal curves (Class 5 – 32.5) with thermal pre-loading to match the safe hot and cold stall times of the motor during operation.
N Series relays are designed to IEC 60255-8 and provide overload protection for cyclic or sustained loads, as well as unbalanced current, single phasing, earth leakage and earth fault protection.
The user has the option of transferring the trip to the incoming MCCB to prevent the contactor opening on high energy faults, ensuring type 2 co-ordination.

Power solutions ensure protection of electrical
equipment and continuity of service during planned and unexpected power outages.
These modular systems include certifi ed low emission (CLE) cast resin transformers, busbar trunkings, enclosures for power switchgear and controlgear assemblies, as well as uninterruptible power supply (UPS) units. An important advantage of selecting Legrand components for effi cient, safe and fl exible power distribution, is the immediate integration between the company’s busbar trunking systems, cast resin transformers and XL³ cabinets.
All power solutions systems encompass the latest technology for energy effi ciency, quality power supply, optimum safety and enhanced aesthetics.
The environmentally friendly, dry type cast resin transformers, transfer electrical power between two diff erent voltage systems at the same frequency, with low environmental impact. These HV/LV transformers off er signifi cant savings on electricity costs and can reduce electricity consumption by up to 20% during off -peak activity.
The absence of fl ammable insulation liquids, the use of self-extinguishing materials exempt of toxic gas emissions, reduced noise levels and low electromagnetic emissions, ensure enhanced environmental protection in all installations.
Standard distribution transformers have rated power between 100 and 3 150 kVA, primary rated voltage up to 36 kV and secondary rated voltage up to 433 V.
Special transformers have rated power up to 20 000 kVA, primary rated voltage up to 36 kVA and secondary rated voltage
on request. Unlike oil transformers, these
cast resin units, with reduced overall size dimensions, can be installed inside buildings and do not require additional building structures. This means optimum fl exibility in any environment. Because no cooling fl uids are necessary, maintenance costs are minimised.
For climate conditions these transformers can withstand severe conditions - E2 - environmental class, C2 - climatic class, F1-fi re-behaviour class.
The transformers are enhanced by pre-fabricated busbar trunking systems, which provide synergy for a direct connection.
These busbar trunking systems, with minimum overall dimensions, provide fl exibility in all areas of an installation, including confi ned spaces. Aluminium or copper busbars and cast resin transformers are equipped with various accessories to provide maximum versatility for any type of power application, including areas which are subjected to high thermal stress and where equipment is sensitive to electromagnetic interferences.
Safety is important in the design of all components.
The absence of fuel masses in the cast resin transformers is
combined with a low fi re load typical of busbars. This feature increases the intrinsic safety of a building against the propagation of a possible fi re.
This fi re retardant range is tested for fi re resistance according to DIN 4102-09 and EN 1366-3 standards.
The connections of high power busbar line elements have reliable mechanical interlocks for easy installation. This design eliminates errors and prevents potential dangers which can occur with conventional systems when starting up the system.
There are other critical devices for optimum protection, reliable distribution and eff ective service continuity in the event of a mains power failure.
These include DMX³ air circuit breakers, DMX³ MCCB’s, supply inverters, isolating switches and XL³ enclosures for sites between 160 A and 6 300 A. XL³ distribution enclosures comply with every part of the standard IEC 61439 to guarantee reliability and total protection of the installation.
The UPS system also ensures continuity of service, in terms of power and back up time.
Optimum sizing of power stages, the latest electronic components and thorough testing of each unit, ensure dependability and safety of the new system.
High performance batteries and an effi cient charging system have extended battery life by up to 50%.This UPS system encompasses three ranges – the Modular series for a reliable power supply up to 120 kVA, the Conventional series up to 10 kVA and the Line Interactive series, which is a UPS system up to 3 kVA.

The MP valve represents the new generation of shut-off valves which fully
corresponds to today’s market demands such as bi-directionality, full bore and minimum maintenance.
The MP is a bi-directional full bore valve which together with its special shut-off design makes it suitable for many different applications – it is a true Multi-Purpose valve.
MP has a one piece body design in stainless steel. For operation reliability in applications with corrosive or clogging media the valve body comes with integrated purge ports as standard. The MP is also supplied with Stafsjö’s retainer ring system which can be combined with several seat materials and this makes it easy to optimize the valve to specific process conditions. It also offers smooth and cost-efficient maintenance. The valve has a gate support and casted bottom support cams to obtain bi-directional sealing. The gate support is available in different materials.
The top work consists of aluminium
The eighth knife gate valve generationbeams and stainless steel tie rods which gives good corrosion resistance and stability at manoeuvring. Several actuator types are available to choose from as standard as well as accessories. All remote operated valves are supplied with gate guards in stainless steel.Sealing principle
When the valve is operated from open to closed position, the gate effectively cuts through the media. This is facilitated by the inner cavity of the valve body and the bevel edged gate. In closed position the gate is pushed against the seat and the gate support ensure a bi-directional sealing together with the bottom support cams that stabilizes the gate.
The gland box is equipped with three layers of TwinPack™ and a box bottom scraper, which gives high operation reliability and prevent the media from reaching surrounding environment.
Keller, leading manufacturer of measuring technology such as isolated pressure
transducers and transmitters, has on offer the new data logger, CTD (conductivity, temperature, depth) - a version of the high-precision DCX level data loggers for depths of up to 200m.
It’s a highly integrated, complete pressure measurement solution for water management. This data logger for long term monitoring, stores over 50 000 time-stamped level measurements, as well as the associated conductivity and temperature readings in each case.
The multi purpose probes have a diameter of 22mm, making them suitable for all sounding tubes with a nominal diameter of 2.5cm or greater.
Data logger measures level, conductivity and temperatureConductivity crucial as standard process value
Water conductivity is a measure of purity, making it an important standard process measurement in the water and sewerage sector as well as in the beverage and pharmaceutical industries. Changes in conductivity are a clear indicator of contamination, for example with particles or salts (chlorides, nitrates, etc.). Typical values lie between >50 mS (salt water) and <5 μS (pure water). KELLER supplies conductivity probes combined with level probes based on pressure sensors. These integrated measuring systems are ideal for checking the ingress of seawater, slurry or fertilizer into groundwater, rivers and lakes, or for performing observation tasks relating to building projects or localized water pollution. The Series DCX 22 CTD level probes with integrated data logger are available with a robust 316L stainless steel housing or other materials, if necessary, for enhanced chemical compatibility.Level measurement: a core competency
KELLER is a leading supplier of maintenance free, battery operated level probes with remote data logger for observations at depths of up to 200 m and optional GSM module for remote access. With level measuring tolerances of ± 0,02 %FS, Keller’s extensive portfolio ranges from data loggers with conventional relative pressure sensors to level probes featuring two isolated absolute pressure sensors that compensate for ambient pressure deviations electrically or using software. All Series DCX-22 products are now available as CTD level probes with integrated conductivity and temperature
sensor. At a rate of one measurement per hour, the integrated lithium battery has a life of up to 8 years.Conductivity probe with six electrodes
In line with Swiss quality standards for pressure sensors, the DCX-22 level measuring probes are equipped with high-precision conductivity sensors. Four platinum electrodes on the outside supply a set alternating current, while two on the inside detect voltage in order to measure the conductivity of the medium. For measuring conductivity, the four measu ring ranges of 0…200 μS/cm, 0…2 mS/cm, 0…20 mS/cm and 0…200 mS/cm, with a measuring accuracy of ± 1 %, can be used. Since water conductivity is highly temperature-dependent, a Pt1000 sensor measures the temperature of the medium directly between the electrodes to a degree of accuracy of 0,1 °C, ensuring that the measured conductivity is accurately standardized to the reference temperature of +25 °C.Measuring software for long-term monitoring
Keller’s Logger 5.1 software is compatible with Windows XP or higher and is included, free of charge. This sophisticated software enables configuration of logger instruments and data download.
Recorder values can be displayed in tabular or graphical form and easily sent to end users or authorities. A particularly notable feature is the ability to graphically display air-pressure-compensated level curves at the same time as conductivity and temperature curves.

A time-saving range of compression glands has been launched locally to allow
installers to draw and secure cables more easily into enclosures without the need for tools.
With the introduction of HeluTop Easy compression glands the installer simply pushes the bottom end through the hole and twists it to secure it equally as tight as hand fastened alternatives.
The installer can also space the glands more closely to save space as no tool entry is required for further fastening.The HeluTop Easy compression glands replace traditional
Clip-through compression glands
threaded locknut compression glands which require the bottom end of the gland to be pushed through the cable entry hole and a locknut secured from the other side (usually requires another person to fasten the glands from the other side).
Traditional glands also need to be spaced suffi ciently far apart to allow spanners or other fasteners to be used to tighten each gland.
Where the old compression glands may have taken two or three minutes to install and mostly required an additional pair of hands on the inside of the cabinet to fasten locknuts, the new HeluTop Easy simply clips and twists
into place in two seconds.On large-scale or complex jobs, the use
of the new clip-in solution can save hours of manpower and further frees manpower to be used elsewhere on the installation. The product’s unique, patented spring/snap system allows easier installations in hard-to-reach areas and in no-access spaces where locknuts can’t be used.
There are no disadvantages only substantial savings in man-hours and the ability to minimize space needed for shoot-through of multiple cables.Advantages• No tools required for installation• No threaded holes required• No locknuts required• Same clamping range • VDE-according to DIN EN62444• Installation in tight areas and no-access
spaces (lock nut side)• Assembly: push cable gland in and turn
clockwise–can be done by hand• Large wall thickness range: 0,5-4,0mm

The exact vapour pressure curves of fi ve diff erent refrigerants are stored in Keller’s
dV-2 Cool digital pressure gauge. This enables the prevailing cooling
temperatures in closed cooling circuits to be derived and displayed by the integrated microprocessor.
Two versions of the digital pressure gauge with stainless steel measuring cell are available: for absolute pressures within the ranges of -1 bar to 40 bar, and -1 bar to 80 bar.
These measure within the compensated pressure range of 0 °C to 50 °C with extreme accuracy and with a tole¬rance of ± 0.1 %FS. Because of the high resolution of 1 mbar and 2 mbar, the dV-2 Cool pressure gauges can also be used for measuring leaks in a vacuum.
Digital pressure gauge for refrigeration performance monitoring
The measurements are clearly legible on the LCD display, which can be rotated to the best viewing direction after installation. Depending on the environment, a special rubber surround is available for protection. Two buttons (Select/Enter) are available for operating the instrument and setting parameters (e.g. selecting the type of refrigerant). Users can also switch between units of bar/°C and psi/°F. After switching on, the battery-operated instrument remains active for a period of 15 minutes and then goes into standby mode. Continuous measurements can be made for approximately two months without changing the batteries.
The WMS-2 HF halogen-free shrink sleeves provide permanent and captive marking of conductors and cables up to a diameter of 38.1 mm. Users have the choice of using marking
sleeves that are shrunk or not shrunk.The shrink ratio is 2:1. For easy use, they area off ered as pre-assembled material in white and
yellow and can be marked on one side with the thermal transfer printing systems from Phoenix Contact.
The continuous carrier material ensures optimum, wipe-resistant printing results. Up to four separate markers are secured per row on a carrier material and can each be
removed separately.Due to the special material selection, the shrink sleeves are also suitable for use in the railway
industry. The DIN EN 45545-2 and NF-PA 130:2007 standards are met.

integrated engineering environment ProSafe-RS R4.01 features AD Suite, the
same engineering environment used with the CENTUM VP integrated control system, allowing the integrated management of CENTUM VP and ProSafe-RS data. With this feature, ProSafe-RS engineers can use AD Suite to design the I/O. AD Suite also has functions for managing the change history and recording changes that save time when renovating systems.
About ProSafe-RSReleased in February 2005, the ProSafe-
RS safety instrumented system helps prevent accidents by detecting abnormal conditions in plant operations and initiating emergency actions such as a plant shutdown. An independent certification body has certified that ProSafe-RS conforms to the IEC61508 international safety standard and can be used in SIL3*³ applications. Unlike conventional safety instrumented systems and distributed control systems, which are regarded as having different roles and functions and operate separately, the operation of ProSafe-RS and the CENTUM integrated control system can be fully integrated. ProSafe-RS is highly regarded by users and has been installed in more than 1,700 projects worldwide over the past 10 years. Yokogawa will continue strengthening the functions of ProSafe-RS to satisfy its customers’ safety instrumented system needs.
*1 A German developer and manufacturer of industrial sensors, process interface solutions, and explosion protection equipment for industrial automation applications
*2 A UK-based company that, as part of the Eaton Corporation’s Crouse-Hinds division, manufactures and develops MTL system infrastructure products and explosion protection equipment for use within the process industries in harsh conditions and hazardous areas
*3 A standard relating to the functional safety of electrical and electronic equipment that was established by the International Electrotechnical Commission (IEC). Safety integrity levels (SIL) 1 through 4 are defined by IEC61508. At SIL3, the risk factor for a plant where safety measures are not in place is in a range between 1/1000 and 1/10000.
An enhanced version of the ProSafe®-RS safety instrumented system (SIS) has been
released. This new version, R4.01, features an exciting expansion of the manufacturer’s lineup of I/O devices and introduces crucial new SIS components. In addition, the FieldMate™ Validator software has been enhanced to work with this latest version of ProSafe-RS.
In the oil, natural gas, petrochemical, iron & steel, and other energy and basic materials industries, accident prevention and protection of the environment are paramount concerns in plant operations. Accordingly, there is a growing demand for SISs that can detect abnormal conditions and safely initiate emergency shutdowns.
To keep pace with the ever evolving business and technology landscape and respond to customers’ needs for solutions that will deliver maximum return on assets and minimise total cost of ownership, the functions of the ProSafe-RS SIS have been strengthened. With R4.01, plant operators can be assured of an optimum engineering environment that spans the entire plant lifecycle, from plant design and the engineering and installation of systems and devices to the start-up of production, maintenance, and renovation. The new features include:
1. N-IO (Network I/O) field I/O device with smart configurable I/O that can handle multiple types of I/O signals
SISs rely on field I/O devices for the transfer of data to and from sensors, valves, and other types of field instruments. Using this data, they can detect abnormal conditions and safely initiate emergency shutdowns. Depending on the instrument model, the type of electric signal used to transfer this data varies. With a conventional FIO device, a compatible I/O module is needed for each signal type.
The N-IO field I/O device developed for
Enhanced version of safety instrumented system for greater efficiency in system configuration and engineering
use with ProSafe-RS fulfills the functions of smart configurable I/O, enabling software marshalling and flexible I/O assignment. It has an I/O module that accommodates multiple I/O signal types and allows configuration of an individual signal type for each point.
Both analog and digital I/O signals, which account for the majority of I/O signal traffic, can be handled solely through software settings. With the N-IO, it is no longer necessary to replace the I/O module, reducing the amount of rewiring that must be done when changing sensor types and/or layouts during a plant revamp.
This significantly reduces the amount of work that has to be performed by plant engineers and maintenance personnel. The N-IO device can also be used together with conventional FIO devices.
In addition, Yokogawa has signed OEM agreements with Pepperl+Fuchs GmbH*¹ and MTL Instruments Group Limited*² under which Yokogawa will receive baseplates and market them as its own products.
These will be used in combination with the company’s N-IO modules and intrinsic safety (IS) isolators procured from the two companies.
Both partners have solid track records in the development of interface products for use in hazardous areas. This tie-up means Yokogawa is able to ensure that the N-IO conforms to the major IS regulations in Europe, Asia, and the Americas.
2. FieldMate™ Validator software tool for use with field I/O instruments to check field device wiring and verify that devices are operating correctly
Upon installation of a field instrument and completion of all wiring, the wiring must be checked. Until now, such verification could only be conducted using the SIS’s engineering screen, which required engineers to wait for all field I/O devices to be installed and the entire SIS, including all operation/monitoring stations and system controllers, to be set up.
The N-IO loop commissioning software, which is used to verify the wiring and relevant operations for any newly installed field instrument or field I/O device, has been modified to support ProSafe-RS R4.01.
When FieldMate establishes a connection with an N-IO device, the FieldMate Validator tool can check in real time the wiring of all field instruments, based on the control loop I/O information in the SIS’s application software, to verify that they are operating correctly. An industry first, there is no longer the need for the entire SIS to be installed to do this, thus saving significant time and providing added versatility in project execution.
FieldMate Validator will be released in early December.

New generation of Ex isolated barriers and Ex analogue signal isolators
The IMX12 device series is a new generation of Ex isolated barriers and Ex analogue signal isolators. With its compact and slim 12.5
mm housing, the device series off ers maximum signal density. This now enables 2-channel temperature measuring amplifi ers in 4-wire PT100 circuits to be implemented via up to four 2-pole terminals – each on the Ex and non-Ex side. Besides the signal density, the IMX12 devices stand out on account of their speed, accuracy and fl exibility.
The IMX12-DI isolating switching amplifi er off ers maximum values in terms of speed. Even input frequencies, which were previously the reserve of special frequency transducers, can be transferred reliably. With up to 15,000 Hz, measured values can be optimally resolved and allow precise measuring without the negative eff ect of a signal conversion.
The developers have given special consideration to the increased requirements with regard to precision: The new electronic design enables the eff ects of factors such as temperature or voltage fl uctuations to be reduced on the IMX12-AI Ex analogue signal isolator. The eff ect of the interface device on the overall performance of a complete measuring circuit is thus considerably less than usual.
The devices of the IMX12 series can be used seamlessly in a range from 10 to 30 VDC. This opens up new possibilities, for example, with a battery or PV current supply. The devices are fully developed and certifi ed in compliance with the requirements of IEC61508 and can thus be used in functional safety loops up to SIL2. All device types have also been individually tested and approved according to the important international Ex standards.

Photoelectric sensor – now even more powerfulIn applications where space is limited
and high precision is required, the new generation of compact O7 photoelectric sensors from ifm electronic come into play. The precise background suppression is particularly reliable, even in the case of highly refl ective objects.
The visible light spot, without scattered light, enables easy alignment of the sensor to the object.
The powerful photoelectric sensors with small design now come with NPN output, ideally suitable for position detection in feeding and handling. The sensors serve as through-beam, retro-refl ective and diff use refl ection sensors with fi xed setting. The diff use refl ection sensor comes with precise
background suppression and a small light spot to detect small objects. The small photoelectric sensors of the O7 series provide an ideal solution for confi ned spaces or for detection of small parts. Users are free to choose between units with PNP or NPN output.
The sensor with a small light spot and the narrow light cone ensures detection of small objects even over long distances. The sensors with fi xed settings are ready for operation immediately post plug and play installation. The diff use refl ection sensors are available with background suppression of 30, 50 or 100 mm range.

They are equipped with Memosens technology that converts the sensor values into a digital signal and transmits it interference-free. The result are reliable measuring values with which the user can
Reliable control of analytical measuring points with 100% signal integrity
take correct and appropriate actions fast to keep the process running under optimal conditions.
Data consistency between lab and processGrab sample analysis with diff erent
technologies as installed in the process, often leads to inconsistencies and measurement discrepancies. Liquiline To Go handhelds allow the use of the same robust Memosens sensors as in the process. This guarantees a full data consistency between lab and process measurements and maximizes the reliability of the grab-sample results.
Suitable for all environmental conditionsBoth Liquiline To Go versions can be
used in the most challenging environments. The robust housing with ingress protection to IP66/67 brings a large improvement for
the safety in many process industries. A fast control of measurement values directly at the sample point is now possible, with a minimized risk of sample contamination. In addition to the CYM290 version, the CYM291 with ATEX/IECEx certifi cation allows process control also in hazardous areas.
Easy handlingDesigned for easy handling, the Liquiline
To Go meters have direct menu-guidance on the display and same function behind the keys for each parameter. Additionally, they facilitate the exchange between diff erent sensors and parameters – directly at the sample point with hot plug and play of pre-calibrated sensors.
Lightweight aluminium power transmission cables
Introducing a cost eff ective and lightweight aluminium power transmission cable to assist alternative power producers to cost
eff ectively plug into the country’s national power grid. The cable is ideal for South African conditions and ticks all the boxes when it comes to reducing cost, simplifying transport requirements, ease of installation
and even reducing the risk of theft that is associated with copper power transmission cables.
The new aluminium power cables are a small fraction of the cost of copper cables and off ers similar performance characteristics and lifespan. Yet the cable is considerably lighter and as a result is far easier to transport and install. In certain instances the light weight of the cable may even reduce the cost of support mechanisms and cable trays.
The cables also have a special fi nely stranded aluminium wire construction, which gives them an added measure of fl exibility and makes them easier to route in confi ned spaces and evidently reduce labour cost and man power.
The cables have specially formulated heat resistant insulation and are UV and oil resistant for installation in harsh environments. To meet international sustainable development and environmental requirements the cables are also manufactured from neutral materials and contain no harmful halogen (LSZH) substances.

Large machine builders and heavy process industries often require multiple terminals
or use PCs to monitor trends and information for their complex applications. With the PanelView Plus 7 Performance terminal, they can consolidate that hardware into a single interface where hundreds of screens, alarms and tags can be conveniently accessed and monitored.
New capabilities in the PanelView Plus 7 Performance model include:
Larger screen option: The Performance model has six screen-size options, including a new 19-inch option – the largest to date from the supplier. The 19-inch screen offers machine builders and end users more display area on which they can design, control and monitor large applications. The Performance
Plus 7 Standard model with a larger screen option, more processing power, expanded connectivity and greater software support.
model also includes new keypad options to complement the terminal’s standard touch screen.
More processing power: A more powerful CPU supports larger displays and larger applications. While the Standard model supports applications with up to 25 screens and 200 alarms, the Performance model supports applications much larger in size and complexity.
Expanded connectivity: With the addition of an embedded Ethernet switch and two Ethernet ports, the PanelView Plus 7 Performance terminal can support a device level ring (DLR) topology for single-fault resiliency.
The terminal also has expanded mobile connectivity.
Remote desktop services enable operators and plant managers on the plant floor to connect to centralised enterprise-level systems such as ERP or MES through a thin-client connection. Embedded VNC and FTP servers allow start-up and maintenance technicians to securely access the HMI from a remote location to troubleshoot a problem, walk through setup procedures, review alarming, manage recipes and more.
In addition, FactoryTalk ViewPoint software – the embedded webserver technology of PanelView Plus 7 terminals – gives plant operators visibility into plant KPIs using a tablet, smartphone or other mobile device.
Greater software support: With video playback support, machine builders and end users can now incorporate helpful videos into the terminal to support operator training and troubleshooting. Microsoft Office viewers and Internet Explorer support give operators instantaneous access to network-based Office files and HTML pages, such as standard operating procedures, directly from the terminal.
The PanelView Plus 7 Performance terminal also retains the benefits introduced with the PanelView Plus 7 Standard terminal. This includes the ability to save projects and critical machine information on an SD card. For example, machine builders can save a single machine’s configuration on an SD card and re-use it for multiple similar machines, while operators can archive machine data for faster terminal replacements and easier troubleshooting.
Both PanelView Plus 7 models work with FactoryTalk View Machine Edition (ME) software to better handle multiple applications on a single terminal. They also use the same clamping technology that allows easy terminal installation and removal without the use of tools. This reduces installation and maintenance time, and minimises the risk of overtightening and damaging the terminal during installation.
New bi-directional knife gate valveThe HL has been developed
to complement an existing product range with bi-directional knife gate valves with through-going gate. The HL is designed to work under similar process conditions as the well known HG and the high pressure valve HP, but in lower pressure classes.
The HL valve represents the first step in the new “Slim line” consisting of compact versions of Stafsjö’s existing product range.Product features
Stafsjö’s knife gate valve HL is bi-directional and tight in both pressure directions. It is a full bore valve with excellent flow characteristic. HL is equipped with a through-going gate for secure shut-off of static and high concentrated media, often a problematic duty for traditional valves. HL is developed for severe
operating conditions with pulp, caustic liquor, reject and waste, but it is also suitable for other applications with powder, slurry and ash.HL has a two piece valve body in stainless steel with purge ports and integrated guiding pads. PTFE body gaskets gives a secure sealing between the body halves. The valve is equipped with a gate in stainless steel and removable retainer rings which simplifies the change of seats. The valve is modular designed meaning that it can easily be customised with gate, seats and box packings according to media and requirements, as well for actuators and accessories.Sealing principle
When the valve is fully open the bore is practically entirely free from cavities and as a consequence flow characteristic
is excellent. In this position the two seats are protected by the retainer rings and the gate, preventing media from entering the valve body.When the valve is operated from opened to closed position, the valve body, gland boxes and the seats gives the gate continuous support for reliable and secure shut-off. Internal guiding pads make this operation smooth and easy. When the valve closes some media can enter the valve body, but it is returned to pipe line when the valve is operated to open position. Stafsjö’s unique gland box packing, TwinPack™, gives a secure sealing where the gate exit the valve body and assures that no media reaches surrounding environment.

An enhanced version of the STARDOMTM network-based control system includes
a newly developed high-speed CPU module for the FCN autonomous controller. Based on the concept of putting forward a product that is Faster, Stronger, Smarter, STARDOM will feature the new CPU module, improved environmental resistance, and an enhanced engineering tool.
STARDOM is a network-based production control system that consists of the FCN autonomous controller and the VDS or FAST/TOOLS SCADA software. Since introducing this system in 2001, Yokogawa has continued to enhance it by adding new functions to satisfy customers’ needs. Combining the reliability of a distributed control system (DCS) with the versatility and economy of a programmable logic controller (PLC), STARDOM is widely used in medium-size manufacturing plants and in geographically distributed applications such as natural oil and gas wells. To date, more than 20,000 STARDOM systems have been delivered.
STARDOM’s FCN autonomous controller will be capable of reliably controlling high-speed equipment such as compressors, large wind power generators, and other types of turbines, and will be able to operate in a wider range of climatic conditions. Moreover, it will include a function that aids engineers in the performance of installation, modifi cation, and maintenance tasks.The Product Features include:
1. High-speed calculation and communication
The processor in the FCN autonomous controller’s CPU module will have fi ve times the processing speed of the processor used in the current CPU module. It will also have a Gigabit Ethernet port for faster communication. This will enable the FCN to reliably control high-speed equipment such as compressors and turbines. With its improved capabilities, the FCN will also be able to stably control more advanced and complex applications. The new CPU module will have a total of four Ethernet ports, facilitating a greater number of connections and the
Network-based control system enhanced through development of new CPU module for FCN autonomous controller
confi guration of redundant communication paths with SCADA systems.
* With redundant CPUs and 120 proportional-integral-derivative (PID) control loops, the average processing speed for each loop will be about 0.2 ms (not including signal processing time). PID control is a feedback control technology that is widely used in basic materials industries such as oil, gas, and petrochemicals. For each loop, temperature, pressure, fl ow rate, and other process data from sensors and other types of detection devices are controlled based on a specifi ed set-point, and instructions are output to valves and other terminals.
2. Strengthened environmental resistanceOil & gas wells are often located in deserts,
mountainous areas, and other locations with severe climatic conditions, and it is essential for controllers to be able to stably operate even in such harsh environments. In addition to a standard model that covers temperatures ranging from 0 to 55ºC, a model covering a range from -20 to 70ºC will be added to our FCN off ering. Moreover, the controller will have a robust fi le system that is not aff ected by sudden power failures.
3. Improved effi ciency of engineering and maintenance work
With the global shortage of experienced maintenance personnel, systems today must off er functions that assist less experienced workers in the correct performance of modifi cation and maintenance tasks. To reduce the likelihood of errors being made during modifi cations, a function that
compares the programs on the FCN CPU module and PCs will be added to the Logic Designer engineering tool. And even if a network connection to a PC is not available, the system can be updated and system information required for maintenance can be obtained by means of an SD card.
Previously, it was necessary to obtain a software license to download each function to a CPU module. The new CPU module will include all necessary functions, so that their download will no longer be required. This is expected to improve engineering effi ciency.About STARDOM
STARDOM is an open network control system consisting of components for control, operation, and monitoring functionality, and its ideal combination of the reliability of a DCS and the versatility and economy of a PLC is highly acclaimed. The FCN autonomous controller, the core of STARDOM, is robust and can be easily implemented in a dual redundant confi guration. The controller is widely used as an intelligent remote terminal unit (RTU) not only in applications that require high reliability and versatility/economy, such as small- to medium-size plants, but also in oil and gas well (upstream) and pipeline applications. The combination of the FCN autonomous controller and VDS SCADA software with a web-based HMI that can be accessed anywhere there is a network connection increases the fl exibility of STARDOM in distributed applications.

The ability to accurately measure over both short and long distances is critical
in sensing applications. Leuze has leveraged technology to enable customers to achieve this no matter the parameters. Two types of Leuze Optical Distance Sensors are available – one using laser or LED light and the other using ultrasonic technology.
Sensors that use laser or LED light are able to quickly and precisely measure distances on a wide range of materials, even at extended ranges.
The Leuze product line-up caters for varying applications and includes a basic laser distance sensor with a measurement range from 20 mm to 500 mm.
This compact sensor, the Leuze ODSL 8, is in a compact metal housing and supplies reflection-independent distance information.
The Leuze PDSL 9 sensor enables accurate measurement even under difficult conditions including glossy objects. Its integrated display
shows the measurement values and facilitates easy adjustment of the sensor.
This sensor offers greater flexibility as it can be used in combination with digital interfaces.
Suitable for large measuring distances, from 60 mm to 25 000 mm, the Leuze ODS 96B optical distance sensor is extremely robust.
Adjustment and configuration is simple done using its integral key pad. The sensor can operate in fast, standard or precision mode depending on the application requirement. It is also compatible with RS 232/485 serial interface.
Achieving maximum precision at long distances can be done using the Leuze ODSL 30 sensor which has a measurement range up to 30 metres, and in applications with bright objects as far as 65 metres away.
With a sensing resolution of 1 mm, the unit is capable of highly accurate measurements over the complete range. The unit features
a referencing function for preventing fluctuations in measurement values.
Ultrasonic technology is most advantageous where there is limited light and using Leuze Ultrasonic Distance Sensors it is possible to reliably detect even partially or completely transparent objects. Measurements can also be done in dusty, hazy or humid environments.
The Leuze 418 Series sensor is best for short range applications and its small cylindrical metal housing makes it suitable for use in adverse conditions. It is possible to synchronise up to 10 sensors on one cable. More compact in design, the Leuze 430 Series sensors is ideal for detecting levels in liquids and bulk material. High accuracy is possible through temperature compensation. The distance information provided by this sensor is highly independent of surface properties.

In addition, Sentient software is web-based, making it possible to email these reports to relevant personnel automatically.
Booyco Electronics is a single source market leader that supplies quality specialised electronic safety equipment, including pedestrian detection systems. Its range of reliable accurate warning, locating and monitoring systems is engineered to operate in the harsh African conditions.
Developing fit-for-purpose products that utilise sensors requires an in-depth
knowledge of sensing technology as well as the ability to identify the correct sensor and integrate it with the electronics and intelligence enabling the desired final product in terms of information, automation and most importantly, increased safety.
These locally manufactured sensors not only meet these exacting requirements but are also designed to operate in the often harsh operating conditions found in Africa on both underground and surface mines.
Accurate measurement of gases is made simple with the South African manufactured ESI Smart Sensor. Significantly, this compact sensing unit, weighing only 1.8 kg, has the ability to measure one of 15 different gases from a single controller. This feature sets the instrument apart from other such units currently in the market.
Gases that can be monitored using this EXia T4 Intrinsically Safe gas sensing instrument include oxygen (02), carbon dioxide (CO2), flammable gases such as methane (CH4) and combustible gases such as carbon monoxide
Magnetic operating principles, in combination with unique signal
evaluation, supported by powerful microcontrollers, make these new encoders a real alternative to traditional photoelectric encoders. Thanks to extended, intelligent functions, the new encoders are flexible for different applications in the field of motion control. The display, operating keys, and user-
More than just encodersfriendly parameter setting and diagnostics via IO-Link make them unique.
Firstly, they can be used as incremental encoders. The resolution between 2 and 10 000 pulses / revolution can be freely set. The units can also be used as counters.
The direction of counting (up / down) and the switch points can also be selected. The third operating mode is used for rotational speed monitoring. The user sets a rotational speed range. The outputs switch when the current value is above or below the limit values allowing the encoders to operate automatically as rotational speed or standstill monitoring systems.
All functions and parameters can be set on the unit via pushbuttons and LED display. During operation the current pulse, count or rotational speed values are displayed according to the set mode. Red or green LEDs immediately indicate if the machine is in the
acceptable range or if limit values have been exceeded. Furthermore, the display can be rotated electronically by 180° which allows flexible installation positions.
Parameters can be set not only directly on the new encoders but also in a user-friendly way via IO-Link. The high shock and vibration resistance enables use for applications in harsh environments.
The cable entry or the rotatable M12 connection for connector units can be used both radially and axially. The selection of the suitable encoder is reduced to the matching flange and shaft - everything else can be freely configured by the user.
There is a basic version for users who use the unit as an encoder and do not need the pushbuttons and the display. This version can also be set completely via IO-Link.

“The purpose of technology is to serve the needs of people”
In a recent interview, Managing Director of Beckhoff Automation Hans Beckhoff shares
his views about his role as an entrepreneur, social responsibility and innovation, whilst explaining the benefi ts of PCbased control technology in context with Industry 4.0 and the IoT.Mr. Beckhoff , many years ago your company started off “small”, but now you have 2800 people who work for you, generating € 510 million in annual sales. How do you personally manage the balancing act between maintaining your technical competence and running such a large company?
From the garage, in which I actually started, through moving to a larger company, you run through a number of diff erent stages and phases; it is a very dynamic process. Every entrepreneur brings along his/her own individual strengths. As a nuclear physicist, I place a special focus on technology. But as I understand it, technology is not a means unto itself. It must always be viewed in the context of the good it can contribute to social developments. What is important to me is the responsibility that we have above and beyond our own companies. There are entrepreneurs who think the same way, but who have ultimately failed, due to the strong growth of their enterprises. How have you achieved this level of success, while maintaining your commitment to social responsibility?
Our success as a company can be directly tied to the performance of our fi rst-class team, which has grown signifi cantly over the years, yet continues to display great loyalty towards the company. You have to be able to think in diff erent dimensions in order to be able to evaluate and assess the impact of decisions you make. Commercial accounting is really not “that” complicated, from the point of view of a physicist anyway (laughs).You’ve been doing this job for 35 years now. Is it still fun?
When I started, I was just 26 years old. Initially, I planned to run the business for ten years and then become the lead singer in a rock band (laughs). But everything takes time, as I have learned over the years. When
you introduce a new technology into the market, or want to set up a company with an extensive global reach, the process required to reach your goals takes a lot longer than you might think at fi rst. Our company is now a large, international community, with great team spirit and solidarity, as well as a strong technological basis. To be honest, I think there is nothing better than that.You mentioned the social responsibility of technology companies. Could you explain what you mean by that?
This involves diff erent levels. The fi rst is that I support diff erent social projects myself as an entrepreneur. Giving something back to the community from the affl uence that we enjoy is simply something that we have to do. Second, as the owner of a company, I assume responsibility for the places where my employees work, i.e. in terms of infrastructure
and common welfare. Ultimately, we want to develop technology to serve the needs of people.
With automation technology, we want to produce products more quickly, more effi ciently, and less expensively, while seeking greater effi ciency in the use of resources. Why?
The number of all products needed around the world is constantly increasing, and people’s purchasing power is also on the rise on a global scale. However, we have only a limited amount of raw materials and resources on this planet to get the job done. Responsible design in automation technology is the key to meeting this challenge.Can that really work? Doesn’t automation reduce the number of available jobs?
What we are talking about here are processes in society as a whole. Let’s assume that there will always be progress, as far as productivity is concerned. As a result, we will be able to produce more goods using fewer resources in the future. What plays a decisive role is the distribution of the growth attained. There are diff erent social interest groups who want to participate, and, as a result, are in competition with one another. In our developed civilization, however, these interests always tend to even out. The proof? Just take a look at our own country of Germany: we are a highly developed nation,
we depend on automation technology as a high-wage location, yet we continue to move closer to full employment.
It takes a lot of innovative strength in order to participate successfully in these developments.How does the Beckhoff process of innovation work?
We are fi rst and foremost a technology company; one third of all our employees are engineers. In addition, we are constantly exchanging information with our customers.
If you walked through our company today, you really would bump into our users almost everywhere. We strive to remain state-of-the-art in our fi eld, implementing the most advanced hardware and software developments in our products. However, the core of our innovation culture revolves around our people: nobody here is afraid to speak openly about their ideas whenever and wherever necessary. Our aim is to cultivate a truly friendly development atmosphere where anyone can speak their minds and discuss concerns democratically. In the end, however, it is the department heads, myself included, who are the “dictators”, tasked with determining the best course of action and making the fi nal decisions. … which of course means, depending on the “dictator”, that some good ideas might fall by the wayside …
That’s the problem with dictators and decision makers (laughs). It’s always after the fact that you see where and when mistakes were made.
However, anyone who makes mistakes all the time will not stay around in management for very long, so we make every eff ort to learn from our missteps and improve in the future.Let’s take a look at the technologies off ered by Beckhoff from a customer’s point of view. Once I decide to use Beckhoff products, do I buy a complete philosophy that I will have to stick to in future?
We provide the user with a complete modular range of hardware and software components for automation. Our modules can be used in a multitude of applications ranging from machine building to measurement technology, and from building automation to stage and show technology.
It’s the users who decide which components out of our “automation kit” they actually want to use. As you know, our automation platform is characterized by openness and interoperability, which means that you can combine Beckhoff systems with products from other vendors without problems. It is interesting to see, however, that our open PC Control automation philosophy seems to attract a certain customer type. Let’s take the Japanese market as an example: If somebody is a committed Mitsubishi user through and through, this is not a fi t for us and our open control concepts. We wouldn’t even try to win over such a user, which in fact
18.6

FB11__SouthAfrica.indd 1 15.01.15 11:44
means that we select our customers through our product philosophy. With some self-confidence I might also put it that way: It is modern and open-minded companies that are a good fit with Beckhoff.If we’re talking with Hans Beckhoff, there’s no way we can avoid the topic of Industry 4.0. Somebody who has relied on open PC-based control systems since the 1980s must feel that Industry 4.0 proves that they were on the right track all along.
Today’s PC-based control systems are very successful in taking full advantage of the
convergence of IT and automation. That was and is “Industry 3.5”, if we refer to the use of electronic control systems on machines as Industry 3.0.
With our philosophy, we are perfectly positioned to fully leverage this convergence of the Internet and automation technologies. Further developments will continue to be exciting, surprising and amazing, especially as concepts from the consumer sector continue to find application in the industrial sector.In addition to the industrial sector, the Internet of Things – imagine an intelligent jam jar or a
talking coat button – will include previously unimaginable things, functions and business models.
However, we have also learned that industrial revolutions do not take place in just a day. We begin to see it take shape only when we look back and analyse what has actually happened. I am sure that, if we fast forward to the year 2040, they will be able to clearly see that the fourth industrial revolution began in the first 20 years of this century!

Announcing Release 3 of the SMARTDAC+® GX/GP series paperless recorders and
GM series data acquisition system. This new release includes a number of new features and capabilities for the SMARTDAC+ system’s GX series panel-mount type paperless recorder, GP series portable paperless recorder, and GM series data acquisition system.
This latest SMARTDAC+ release includes an advance reminder notification and calibration correction feature that will help customers in the heat treatment industry comply with the requirements of the National Aerospace and Defense Contractors Accreditation Program (Nadcap) and the SAE AMS2750E standard, and options that facilitate communications with a variety of industrial equipment, a key requirement for the Industry 4.0 initiative. In addition, the release features multi-batch capability, a DC power supply module (GM series only), and a pulse input module, and also adds support for a communications protocol used by supervisory control and data acquisition (SCADA*¹) systems and human machine interfaces (HMIs).
Recorders and data acquisition systems (data loggers) are used on production lines and at product development facilities in a variety of industries to acquire, display, and record data on temperature, voltage, current, flow rate, pressure, and other variables. The Company offers a wide range of such products, and is one of the world’s top manufacturers of recorders. Since releasing the SMARTDAC+ data acquisition and control system in 2012, the range has been strengthened with the release of a variety of recorders and data acquisition devices that meet specific market needs and comply with industry-specific requirements and standards.
Aerospace companies often need to certify that their heat treatment and other
Paperless recorders and data acquisition systemindustrial processes are Nadcap compliant. This SMARTDAC+ release includes a new option that addresses this need as well as options that facilitate connectivity with other types of industrial equipment, a key requirement for achieving the objectives of the Industry 4.0 initiative.
With this release, four (4) new firmware options and two (2) new optional hardware modules (a pulse input module and a GM series DC power supply module) are available. The key features of the four firmware options are as follows:
1. Heat treatment process option for Nadcap and SAE AMS2750E certification
Nadcap and the SAE AMS2750E standard specify the pyrometric requirements for thermal processing equipment that are used in the heat treatment industry. In heat treatment processes where sensors, recorders, and data loggers are mounted directly on the heat treatment equipment to monitor their operating temperature, it is important for their calibration cycle to be clearly displayed. It is also important with accuracy tests for any calibration errors to be clearly displayed. In addition to having these capabilities, this heat treatment process option facilitates the management of calibration schedules. It can also set error compensation values for individual sensors, recorders, and data loggers, and record these values together with the measurement data. This option makes it easier for companies to obtain and maintain Nadcap and SAE AMS2750E certification.
2. OPC-UA and SLMP communications options
Release 3 includes a server option that complies with the OPC-UA communication standard necessary for Industry 4.0 automation. This enables measurement data stored on general-purpose data servers to
be accessed directly by SCADA systems and HMIs. With this option, the GX/GP series paperless recorders and the GM series data acquisition system can function as subsystems for the transfer of data from field sensors and measuring instruments to upper level systems. Also available with release 3 is a seamless message protocol (SLMP*²) communications option that eliminates the need for a separate module or program to connect with SLMP-compliant PLCs via an Ethernet link.
3. Multi-batch recording optionProcesses in the heat treatment, food/
beverage, and pharmaceutical industries often require the use of more than one recording instrument to capture data on multiple batch processes. With the multi-batch option, a single recording device can record data from multiple batch processes, with the ability to individually control the start and stop of recording for each process. Furthermore, as SMARTDAC+ I/O units can connect to a network via Ethernet cables, access to multi-batch data distributed over a wide area is assured. About SMARTDAC+
SMARTDAC+ stands for smart data acquisition and control. SMARTDAC+ offers input and output modules for a variety of signal sources and widely supports manufacturing processes and product performance evaluation testing.
*1 An industrial monitoring and control system
*2 A widely used protocol that enables Ethernet applications to communicate with CC-Link IE compliant instruments (CC-Link IE is an Ethernet-based integrated open network). This protocol enables communication without regard to network hierarchy or boundary.
