Not all IR Gas Detectors are the sameThe Simrad GD10P roots go back to Simrad Optronics, a world leading Norwegian manufacturer of night vision equipment since 1960’s. They have mastered the use of the IR technology. In the early 1980’s Oil & Gas operators approached them for a solution to replace problematic catalytic gas detectors. The very first IR gas detector model was introduced in 1986 and it was an instant success with offshore operators. This makes Simtronics as one of world most proven IR gas detection technologies. The Simtronics GD10 Detectors are sold with an unmatched 15 years warranty on the SimSource™ IR sources.
The GD10P concept is based on measurement of IR radiation passing through a volume of gas. It employs a dual beam, dual wavelength measuring principle with separate optical detectors for maximum stability and reliability. Using two solid-state IR sources instead of a filament lamp ensures high reliability and long-term stability with no regular maintenance or calibration required.
Radiation from two infrared sources passes through two narrowband filters selecting a measuring wavelength and a reference wavelength. The sources are electronically chopped. Radiation is divided by a beam splitter into an internal and external path. The internal path is viewed by the compensation detector, and the external path is viewed by the measuring (main) detector. The compensation detector monitors and compensates for drift in sources or detectors. The main detector monitors the external measuring path and detects whether the selected gas is present.
The four signals, two from the compensation detector and two from the main detector, are amplified, digitised and fed to the microprocessor. The signals are used by the microprocessor to calculate the gas concentration. The gas response is then linearized and presented as a voltage, a current or a digital output signal. Internal signals are compared with test limits to monitor electronics and optical parts. If values outside the test limits are found, specific error messages are given.
Optical filter characteristics remain constant over time, and drift in the other components is monitored and compensated by the dual wavelength, dual path concept. This means that the zero and gas span factory calibration will remain stable regardless of component drift, and that the detector needs no manual recalibration after factory calibration
The unique SimSource™ is a Simtronics patented solid state Silicon IR source used in all Simtronics IR gas detectors. This technology makes the GD10P the only Point IR Gas detector that does not require field calibration or recalibration during its lifetime. The GD10P has no user adjustable parts. It has been designed to require a minimum of maintenance. The only necessary maintenance is to inspect visually that the Weather Protection is not clogged in heavily contaminated areas.
In addition the GD10 uses Lead Selenide detectors which are much more stable when exposed to rapid temperature changes than Pyroelectric sensors used in other IR gas detectors. Lead Selenide will NOT give false readings if the detector is exposed to vibration.

Control of safety risks at gas turbinesThe fuel supply system to a gas turbine has to be a high-pressure system. Normally the operating pressures are ranging from 30 barg to 50 barg, depending on the design. The fuel system is often very complex. The fuel is supplied to one of more annular distribution manifolds again connected to several individual burners. All the bellows, flanges and flexible pipes are potential leakage sources. The possibility of one or more leakages is highly present. Even small local leaks may over time lead to accumulation of a flammable mixture of fuel and air within the turbine enclosure.
Gas detectors should always be installed in the ventilation outlet of the turbine enclosure. This is the best location for gas detection because any leaking gas from inside the enclosure will be drawn to the detector in the duct together with the ventilation air.
Alarm levels for gas detectors placed around gas turbines The alarm levels must be dedicated by their purpose according to HSE (Health & Safety Executive in UK). In the Guidance Note PM84, Control of safety risks at gas turbines used for power generation. HSE recommends that the setting for the gas detector in the ventilation outlet from the enclosure, should be set as low as reasonable possible, and that the level for this detector should be below 5% LEL and not exceeding 10%LEL. The level for high-level trips should also be set as low as reasonable possible, but no higher than 25%LEL.
This application requires reliable, stable and accurate gas detectors. The GD10PE is calibrated to 0-20%LEL. An alarm level of 5%LEL amounts to 25% of full scale.
PM84 Guidelines:Detectors should be sited in the ventilation outlet duct where detection can be guaranteed.
External calibration points should be considered to maintain reliability without plant shutdown.
Gas detectors in ventilation outlet should be set to their lowest practicable level, preferably below 5% LEL but not exceeding 10% LEL.
In the event of a gas alarm the ventilation should be run at maximum whilst safe plant shutdown is achieved.
Gas levels no higher than 25% LEL should initiate automatic GT trip with gas supply valves being fully closed.

GD10PE HIGH SENSITIVITY POINT IR GAS DETECTORThe GD10PE is designed for critical applications involving large volumes of air with high velocity. In places where you need fast reliable detection of low gas concentrations, GD10PE is in a class of its own.
The versatile GD10PE is suitable for monitoring, among others, the HVAC air intakes of living quarters, temporary refuges and local equipment rooms. In addition the ventilation air and combustion air intakes of gas turbines can be monitored along with the ventilation air extract duct, the only location where you can guarantee to detect a gas leak on a turbine package.
With a measuring range of 0-20%LEL the GD10PE is 5 times more sensitive than standard point detectors. This, and a response time in the region of 1 second should cover even the most demanding requirements.
It can tolerate continuous operation at 85°C inside the duct.
IECEx certified, suitable for SIL2 systems and is supplied with 5 years warranty and 15 years on IR sources.

Open Path Toxic Gas DetectionHydrogen sulphide (H2S) has one of the most readily identifiable odours known to the petrochemical and waste water industries. The familiar “rotten eggs” smell is detectable to the human olfactory system at concentrations below one part per million (ppm). Hydrogen sulphide is both toxic and flammable; research has shown that long term exposure to concentrations above 1 ppm can irreparably damage the sense of smell. Concentrations in excess of 100 ppm can lead to an immediate loss of smell; those over 300 ppm are potentially fatal.
It is known that gases and vapours are transparent to visible light but block light of specific wavelengths. The interaction between absorption and wavelength generates a profile or “fingerprint” for each gas molecule; the Beer-Lambert law defining the absorption physics from which a gas concentration can be quantified.
Methane detection has been achieved due to the strong absorption of its hydrocarbon (H-C) component bond and the commercial availability of IR sources and filters. It should be noted these devices are really hydrocarbon, not methane detectors.
Traditional IR sources provide a wide band of light that in essence “wash out” some absorption lines of a given gas species; a new approach was therefore needed to improve specificity. Intensive research has lead us to develop a technique using a single tunable laser diode source coupled with advanced software algorithms to pinpoint specific “wavenumber” where there is little or no interference from other gases.
Modern industrial toxic gas detection systems tend to use one of two main technologies, these being electrochemical cell (EC) or metal oxide semiconductor (MOS). Each technology has their own merits with the selection mainly depending on the local environmental conditions where the unit will be installed.
Tuneable Laser DiodeThe laser diodes used for gas detection have emerged from high capacity fibre optic telecommunication equipment where e.g. multiple 10 Gbit/s channels are packed into a single optical fibre, separated by wavelength. This wavelength separation demands accurate tuning of the laser diodes, and it is this tuneability that is used to achieve gas detection by scanning gas absorption lines. As the light source bandwidth is very narrow, almost down to a single wavelength, it is possible to pick up single absorption lines and thus achieve gas detection with virtually no cross sensitivity to other gases.
A laser bandwidth is approximately 0.0001 nm compared to typically 100 nm for conventional IR gas detectors. Where a conventional IR gas detector is tuned to a major absorption band for the target gas, a laser based detector looks for single absorption lines.
Once the absorption line of interest has been identified a best match laser diode is selected which must be capable of scanning an active and reference wavenumber. The reference is selected to provide a datum point using a commonly available atmospheric gas, namely carbon dioxide.
The laser is finely tuned to the wavenumber of interest, by temperature, ±5 mK, a ramp current is then employed to sweep the region of interest, typically 0.2 - 0.3 nm. The sweeps this region at 1 kHz and continuously monitors the active and reference wavenumber.
The selectivity of laser based gas detection, and the fact that one laser may be used to cover both target and a reference gas like CO2, gives a very low “probability of failure on demand.” This allows the detectors to be employed with high availability and minimal maintenance in Safety Integrity Level (SIL) rated systems.

Open Path Infrared (IR) Gas DetectionAs opposed to point detectors, the length of the measuring path of an open path detector is different from installation to installation. Normally, the measuring path is too long to be filled with a homogeneous gas concentration. In principle, an open path detector measures the total amount of gas present in the measuring path. Therefore, an open path detector will not distinguish between a small gas cloud with high concentration and a large gas cloud with a low level of concentration.
If the sensitivity of an open path detector is to be measured in % LEL, the length of the measuring path must be fixed and the gas concentration must be homogeneous over the entire measuring path. As open path detectors from practical reasons seldom are installed with fixed-length measuring paths and gas concentrations are not normally homogeneous over the whole measuring path, gas sensitivity is not given in the same way as for point detectors.
The gas response of open path detectors is given in LEL x metres (abbreviated LELm), which is the product of the concentration and extension of the gas cloud. Thus, gas sensitivity becomes independent of the length of the measuring path, which makes it easy to compare the sensitivity of open path detectors.
As an example, a gas cloud with a concentration of 1 LEL and an extension of 5 m will give a reading of 5 LELm. Correspondingly, a gas cloud with a concentration of 5 LELm and an extension of 1 m will give a response of 5 LELm.
Most Point flammable gas point IR detectors are calibrated for methane gas and monitor the region around 3.3 microns. Line of sight (LOS) open path detectors typically monitor the region around 2.3 microns. The 3.3 and 2.3 micron regions are known as fundamental and overtone wavelengths.

Ultrasonic Gas Leak Detectors Acoustic/ultrasonic gas leak detectors compliment traditional gas detection methods and are used in refineries, gas plants and offshore installations.Ultrasonic gas leak detectors do not detect specific values of LEL or ppm, rather, they respond to the sound generated by escaping gas at ultrasonic frequencies.Such signals are generated when leakage occurs from a pressurised pipe or vessel, with a driving pressure of at least 2 barA. The detected ultrasound is proportional to the leak rate (mass flow rate) of the gas. In basic terms, the greater the leak rate (large leak), the greater the ultrasound emitted.
Mapping Detection area covered is governed by known criteria:• Physical positioning of the detector• Background noise level on the plant• Pressure & temperature of gas in area to be monitored.• Leak Classification (Kg/s)A mapping survey allows ProDetec to produce a report which will indicate the preferred detector location and the exact area covered by each detector. A Survey Report is then produced which would Map the surveyed area together with proposed sensor positioning and advice on alarm set points.The same can be achieved for Greenfield Sites by utilising data from a growing library of typical plant and equipment ultrasonic noise levels.

Sampling SystemsOur sampling systems provide a unique solution to the complex problem of accurately monitoring gas and/or smoke ingress into areas where it is not practical or safe to position a detector directly.
Every aspirator is custom built from standard module components.
Our aspirators use minimal compression fittings which help to reduce maintenance costs by reducing leak paths. No other aspirator supplier offers such a system.
If an instrument air supply is not available a pump operated aspirator can be provided.
When to use an aspirator?• Inaccessible and hard to get to areas
• Where ambient temperatures are too extreme for field devices, particularly point infrared, electrochemical and optical smoke detectors
• Duct monitoring where high air velocities increase response time of diffusion based gas detectors
Combustible and toxic gas detection (as well as smoke detection) can be mixed in a single cabinet. We have Self compensating duct probes can be supplied to provide an accurate representation of any duct being monitored.
