1 Product description

These process pressure transmittersrepresent an efficient, proven sensorsystem for process pressure meas-urement. Ongoing development inconjunction with the latest advancesin materials science guarantee qual-ity and precision. Beside theirprocessing quality and high ageingresistance, the pressure transmittersare characterised by process fittingsexactly adapted to the measurementconditions. One common feature ofthe VEGA pressure transmitters is theincorporation of the completely dry,ceramic-capacitive CERTEC® meas-uring cell with a diaphragm of highpurity sapphire ceramic®.

Maximum accuracy and excellentlong-term stability characterise thesepressure transmitters. In cooperationwith various industries, pressuretransmitters for sophisticated appli-cations have been developed. Spe-cially adapted materials and designvariants enable their use in corrosiveand abrasive products as well as inprocesses with increased aseptic re-quirements (food processing or phar-maceutical industry).

The sensors are used in all industries:- Chemicals- Pharmaceutical/Cosmetics- Petrochemicals- Water/Waste water- Foodstuffs- Beverage industry- Paper industry- Shipbuilding- Printing industry- Mining- Mechanical engineering

Several versions for the output of themeasuring signal are available:- 4 … 20 mA- HART®

- Profibus PA

Process pressure transmitters arealso available in different adjustmentand indication versions.

Certified instruments are available foruse in hazardous areas, in pressu-rized vessels, in hygienic products oras part of an overfill protection sys-tem. They are certified acc. to:- CENELEC EEx ia IIC- PTB Ex-Zone 0 (Germany)- EHEDG- WHG- 3A- FDA

2.1 Pressure measuringprinciples

There are basically three types ofpressure measurement:- absolute pressure measurement- relative pressure measurement- differential pressure measurement.

The process pressure transmitters in-troduced in this product informationbrochure are available as absolute orrelative pressure transmitters.

2 Function and application

Absolute pressure measurementIn absolute pressure measurement,the absolute vacuum is the referencepressure to which all measured val-ues refer. In an unpressurised state,these pressure transmitters indicatethe existing air pressure. This is whythey can be also used as barometers.

Relative pressure measurementPressure measurement according tothe relative pressure measuring prin-ciple is the most commonly usedmeasuring technique. The existingambient pressure (air pressure) is thereference pressure. Relative pres-sure transmitters thus indicate zerobar in an unpressurised state.

Differential pressure measure-mentDifferential pressure transmitters de-tect the difference between two pres-sures. The two pressures to be de-tected are transferred to one sensorelement through two separate proc-ess fittings.

2.2 Principle of operation ofthe measuring cell

Plate capacitor principle

The ceramic measuring cellCERTEC® is manufactured from thenewly developed sapphire ceramic®

material. A ceramic diaphragm isbonded to the ceramic base elementwith solder glass. The ceramic baseelement and diaphragm are printedinside with a gold layer and form theplates of the capacitor.

Absolute Relative Difference

P1 P2

P P

Pref.

P = 0(Vacuum)

The "plate distance" between the ce-ramic base element and the dia-phragm is 16 µm. The diaphragmmoves in a microscopically small dis-tance over the measuring range andcauses capacitance changes bymeans of the varying plate distance.

This capacitance change is detectedby an ASIC (Application Specific Inte-grated Circuit) and converted into apressure-proportional signal by theintegrated oscillator with microcon-troller. The exact, digital processingof measured data with maximumresolution ensures outstanding accu-racy.

Self test and self monitoring

To increase reliability, all pressuretransmitters monitor themselves con-tinuously. The measured value, thetemperature and the operating volt-age are checked.

The process pressure transmitterswith ceramic CERTEC® measuringcell also offer in addition the advan-tage of a continuous self monitoringright up to the diaphragm: Meas. andreference capacitance of the meas-uring cell are in a defined ratio overthe entire measuring range. Any de-viation from this ratio is a reliable indi-cator of failure of the measuring cell.

If failures or malfunctions are de-tected during these routines, a faultsignal is triggered. The fault signalcan then be processed in the signalconditioning instrument or in the con-nected signal processing (e.g. PLCsystem).


Overload resistantThe CERTEC® sapphire ceramic®

measuring cell exhibits overload re-sistance up to 150 fold. A flowing liq-uid suddenly blocked by a valve clos-ing in 20 ms, produces local shockwaves with 20 to 40 times the nominalpressure. For a few milliseconds, thepressure rises to levels that can de-stroy sensors with a lower overloadresistance.

Features of the CERTEC® measur-ing cell• Dry, ceramic-capacitive sensor el-

ement of sapphire ceramic® (99.9 %Al2O3).

• Versions for relative and absolutepressure (measuring ranges from -1 bar … 0.1 bar … 60 bar).

• Up to 150 fold overload resistance(also dynamic!).

• Excellent long-term stability andreproducibility.

• Excellent abrasion and corrosionresistance.

• Minimal internal air volume.• Absolutely flush mounting possible.• FDA tested.• Integrated continuous self-monito-

ring.• Integrated temperature sensor.

Function and application

2.3 Features of the ceramicmeasuring cells

The sapphire ceramic® developed byVEGA consists of a special fine-grained aluminium oxide with an av-erage grain size of only 2.5 µm, incontrast to other ceramics that have agrain size of more than 30 µm. With apreviously unreached purity of99.9 %, the CERTEC® sapphire ce-ramic® exhibits undreamt-of me-chanical and chemical properties:- completely hysteresis-free- ideal elastic properties- extremely overload resistant- maximum corrosion and acid re-

sistance- resistant to very abrasive products- maximum hardness- absolutely ageing-resistant

Chemically resistantIn field tests and test series using10 % caustic soda solution, hydro-chloric acid, sulphuric acid, phos-phoric acid and nitric acid for artificialageing, sapphire ceramic® hasproven to be a highly corrosion resist-ant material.

Abrasion resistantAbrasion is basically a machiningprocess in which very small hard par-ticles remove microscopically smallchips. Ceramic is resistant to thisabrasion process.

Ten times harder than stainless steel,the sapphire ceramic® diaphragm ef-fectively prevents wear, abrasion ordamage of the diaphragm by micro-scopic chipping. Whether caused bypaper pulp carrying metal particles,which can act like grinding paste, orby nut chocolate which, due to nutfragments, can be extremely erosive,the hard ceramic material can with-stand any form of diaphragm abra-sion.

Absolutely flushThe seal concept unique in compari-son to other sensors, enables perfectflushness, a critical factor in manyapplications.

In the food processing and pharma-ceutical industry, flushness is the keyto solving the well-known problemsregarding the instrumentation of aplant. Beside the expected high dura-bility, accuracy, long-term stability,ruggedness and user-friendly setup,a sensor must also meet utmost hygi-enic and aseptic requirements. GMP,GHP, FDA, sterilisation, EHEDG and3A are the requirements measure-ment technology always has to meetin the food processing and pharma-ceutical industry. The sensor must bereliably cleaned or sterilised with CIP(Cleaning in place) and SIP (Sterilisa-tion in place). Perfect flushness is thesolution.

Dirt and impurities mainly stick inpores, gaps, shoulders andscratches. Such are avoided by theflushness and surface quality.

3.2 Electronics versions

Connection technologies

There are basically three differentconnection technologies for VEGAprocess pressure transmitters.

4 … 20 mADependent on the pressure, the proc-ess pressure transmitter consumes acurrent between 4 mA and 20 mA.This current is a measure on the pres-sure or the level (e.g. 4 mA corre-spond to 0 bar, 20 mA correspond to10 bar).

HART®

Pressure transmitters with HART®

technology also consume a supplycurrent between 4 mA and 20 mA,which corresponds to the acting pres-sure. In addition a digital signal con-taining information from the pressuretransmitter, e.g. on the acting pres-sure, is superimposed on the current.At the same time, these signals arealso used to transmit commands, e.g.for adjustment.

The operating mode "Multidrop" isalso possible. Several instrumentsare connected in parallel to one two-wire cable (max. 15). Each instrumentmust have an address for identifica-tion. The current consumption ofeach instrument is 4 mA.

Profibus PAProfibus PA is an open field bus espe-cially for process technology. Withthis it is possible to connect severalsensors, also in Ex area, to one buscable. The connection is carried outin two-wire technology, but with spe-cial cable types.

A diskette with the sensor master file,to enable connection to the Profibussystem, comes with the pressuretransmitter. This file contains informa-tion required for programming, e.g. ofa PLC. These files are also availableon the VEGA homepage as downloadfiles (www.vega.com).

Adjustment versions

The VEGA process pressure transmit-ters can be adjusted (configurationand parameter adjustment) in differ-ent ways depending on the instru-ment version.

Mounting

5 Mounting

It is necessary to use a gasket formounting. This is either supplied withVEGABAR or must be provided by theuser.

Compensation of the atmos-pheric pressureThe atmospheric pressure of instru-ments used for gauge measurementis compensated via a breather facilityintegrated in the housing.

5.1 Mounting instructions

VEGABAR can be mounted in any po-sition. The cable entry should pointdownward to avoid humidity ingress.For this purpose, the housing ofVEGABAR 40 … 44 can be rotated by330° against the mounting body.

5.2 Mounting VEGADIS 10

VEGADIS 10 can be mounted in thefollowing ways:- on carrier rail 35 x 7.5 acc. to

EN 50 022- on mounting bracket or on the wall.


Electrical connection

6.1 Connection instructions

The electronics in VEGABAR requiresa supply voltage of 12 … 36 V DC. It isprovided in two-wire technology, i.e.supply voltage and current signal arelooped via the same two-wire cable tothe terminals.

This external energy is provided via aseparate power supply unit:- power supply unit, e.g. VEGASTAB

690- processing unit with integral DC-

current source (e.g. active DCS-input)

- VEGAMET or VEGADIS 371

Make sure that the external supply isreliably isolated from the mains cir-cuits acc. to DIN VDE 0106, part 101.The above mentioned VEGA instru-ments meet this requirement and pro-tection class III is hence ensured.

The external supply must provide aterminal voltage of at least 12 V to thetransmitter. The actual terminal volt-age on the transmitter depends on thefollowing factors:- output voltage of the external power

supply under nominal load.- electrical resistances of the con-

nected instruments in the circuit(see connected instruments, loadresistance).

6 Electrical connection

Note the following instructions forelectrical connection:- The connection must be made acc.

to the local installation standards(e.g. in Germany acc. to the VDE-regulations).

- The terminal voltage must not ex-ceed 36 V to avoid damage to theelectronics.

- The electrical connection is pro-vided with a reverse polarity protec-tion.

- The wiring between VEGABAR andpower supply can be made withstandard two-wire cable.

- If strong electromagnetic interfer-ences are expected, screened ca-ble is recommended. The screen-ing must be earthed at one side onthe sensor.

- If overvoltages are expected, werecommend the installation of VEGAovervoltage arresters.

- A seal suitable for the cable must beused in the cable entry.

- With instrument version EExd (pres-sure-tight encapsulation) screenedcable must be used for the instru-ment connection. Observe themounting regulations.

Connection instructions forProfibus PA instruments

The electronics in process pressuretransmitters for Profibus PA requires asupply voltage of 9 … 32 V DC. Thesupply voltage and the digital outputsignal are led via the same two-wireconnection cable to the terminals.The external energy is provided by asegment coupler.

Note the following instructions forelectrical connection:- The connection must be made acc.

to the local installation standards(e.g. in Germany acc. to the VDE-regulations).

- The electrical connection musthave a protective measure againstpolarity reversal.

- The connection of field instrumentsis generally made via T-adapters onstubs.

- Screened cable is recommendedfor connection (cable types seechapter "Technical data"). Theshielding must be grounded on bothends (on the T-adapter and on theconnection housing).

- For use in Ex areas, the installationregulations must be observed.



1) If a screened cable is used, the screen should be connected to function ground in the terminal box and the ground terminal on the housing exterior groundedaccording to the instructions. Both terminals are connected to each other in the housing.

Hot steam

With VEGABAR 40, hot steam can bemeasured without the use of isolatingsystems for temperature decoupling.

For this purpose, VEGA offers as ac-cessory special siphons acc. to DIN16 282 with connection tap on thepressure extraction side (see chapter"9 Accessories"). The function of thesiphon is to cool the process tem-perature of the hot steam. The coolingis done via a condensate chamber ina U-tube or a ring tube.

In practice, the rule of thumb is as fol-lows:A siphon in ring or U form filled withcondensate can cool the medium(steam) by approx. 100°C.

If there are still higher product tem-peratures in front of the siphon, a tubeof sufficient length must be providedbetween the siphon and the measur-ing instrument for heat dissipation.

In power stations, for example, tubesthree or four meters in length, de-pending on the steam temperature,are often welded in to provide coolingdistance.

Mounting instructionsFor wall, tube or stand mounting ofVEGABAR 40, VEGA offers a bracketfor measuring instruments acc. to DIN16 281, as well as the requiredadapter as supplementary accessory(see chapter "9 Accessories").


Pressure transmitters with isolating diaphragms

8 Pressure transmitters with isolating diaphragms

8.1 General information onisolating diaphragms

Isolating diaphragms transfer themeasured pressure of the substanceto the pressure transmitter, if for cer-tain reasons, the pressure transmittershould or cannot come into contactwith the measured substance.

Isolating diaphragms and pressuretransmitters form a complex measur-ing system, the accuracy of which isinfluenced by many factors. The opti-mum dimensioning for solving an in-dividual measuring problem can onlybe carried out if the operating condi-tions are exactly known.

The goal of this presentation is toshow the problem involved with iso-lating systems and to give basic infor-mation on possible solutions.

8.2 Applications

There are many reasons why a sepa-rator between measured substanceand pressure transmitter might benecessary:• The measured substance is corro-

sive. The sensor element cannot beprotected effectively.

• The measured substance is highlyviscous. The often inevitable deadzones of the pressure transmittercause measuring problems.

• The measured substance crystal-lizes, especially in dead zones.

• The measured substance polymer-izes. Connection tubes to the pres-sure transmitter can clog.

• The measured substance is hetero-geneous, e.g. fibrous; buildup andunmixing are caused in dead zones.

• The measured substance has a veryhigh temperature. An unwanted tem-perature increase is caused in thepressure transmitter.

• The measurement location is unfa-vourable. Due to space reasons,the pressure transmitter cannot bemounted or read correctly. The pres-sure transmitter is connected to theisolating diaphragm via a capillaryline so that mounting in a more fa-vourable place is possible.

• Hygienic regulations must be ob-served for the measured substance.Bacterial growth can result in cor-ners which are difficult to clean.

8.3 Function

The function of an isolating dia-phragm is best shown in a diagram.The pressure to be detected is trans-ferred via the separating diaphragmand the oil filling to the sensor ele-ment.

8.4 Selection criteria

Isolating systems have a characteris-tic temperature reaction which cansubstantially influence the measure-ment. To reduce this influence to aminimum, some important factorsshould be considered.

First of all, the diaphragm diameter

should be as large as possible. Rea-son: Diaphragms with small diam-eters are more rigid than those withlarger diameters. The temperaturedependent expansion of the isolatingliquid is better compensated by a dia-phragm with larger diameter (larger =more elastic) as the diaphragm com-pensates a part of the isolation liquidexpansion. This selection criterion isof course limited by the required proc-ess connection.

The second possibility for optimisingthe temperature reaction is the thick-ness of the separating diaphragm.Here is valid: the thicker the dia-phragm, the worser the temperaturecoefficient! Usual diaphragm thick-nesses are between 50 µm and100 µm. However the mechanicalruggedness should be always takeninto account, as a thin diaphragm canbe easily damaged by carelessnessor substances containing solids.

The selection of the fill fluid (e.g. sili-cone oil, water-glycerine) also offersthe possibility to influence the tem-perature reaction, as the liquids havedifferent temperature expansion coef-ficients. The characteristics of differ-ent fill fluids are discussed in detaillater on.

The necessary oil volume for fillingthe isolating system must also be con-sidered. However, the mechanicaldesign is usually such that the re-quired oil volume is already mini-mised and therefore no realisticoptimisation possibilities exist.

In general, the selection of the sepa-

rating diaphragm material also of-fers a means for optimisation. In prac-tice, however, it is a matter of fact thatthe diaphragm material is primarilydetermined by the product compat-ibility.

Additional characteristic propertiesresult from the design of the isolatingsystem.

Quick temperature changes willreach the sensor element consider-ably damped. This eliminates thesometimes unfavourable temperatureshock reaction of the CERTEC® celland also reduces temperature-re-lated ageing effects. One disadvan-tage of the temperature decoupling isthat the read-out temperature valuescorrespond only in a few cases to theactual product temperature.

Another aspect is the noticeable re-duction of dynamic pressure peaksby the transmitting oil, which also hasa positive effect on the reliability of thepressure transmitter.

8.5 Error calculation

The influence of an isolating systemis primarily determined by the tem-perature of the isolating liquid.

The total temperature error is the sumof the temperature dependencies ofthe pressure transmitter and the iso-lating system.

TKTot = TKIsolating system + TKPressure transmitter

Example:

The selected pressure transmitter has- a nominal range of 0 … 1 bar and- a TK of 0.05 %/10 K (see technical

data).This corresponds to a TKPressure transmitter

of 0.5 mbar/10K.

The isolating diaphragm used has atemperature influence of 2.7 mbar/10 K

TKTot = TKIsolating diaphragm + TKPressure transmit.

= 2.7 mbar/10K + 0.5 mbar/10 K= 3.2 mbar /10 K

The determined total temperature er-ror corresponds therefore to 0.32 %/10 K!

Due to these dependencies, there arelimitations on the available nominalmeasuring ranges, depending on thenominal width of the isolating system.This limitation results from the factthat the temperature errors of the iso-lating systems must be seen as abso-lute values and therefore have a con-siderable influence on the total errorsmall nominal measuring ranges.

To reduce the total error of the pressure transmitter to a minimum, it is necessary to use a pressure transmitter in the bestavailable accuracy class (especially for small measuring ranges as well as small nominal widths!).

The following table gives an overview of the temperature dependencies of different standard versions.

CA TRI-Clamp 2" PN 10 7.0 7.6

When using capillary lines, an additional error of 0.1 … 15 mbar/10 K per meter must be considered in general (also depend-ing on the diameter of the separating diaphragm). In these applications, a requested temperature gradient between meas-urement loop and mounting location of the pressure transmitter results, so that an examination of the temperature influencesis very difficult to present and is therefore not listed in the table.

The error values relate to the following products:Silicone oil, vegetable oil, high temperature oil, medical white oil (Essomarcol).

When using water-glycerine, the error values will be reduced by a factor of 0.65 as this fill fluid has a lower temperatureexpansion coefficient.



Isolating systems extend the producttemperature range of pressure trans-mitters considerably. Therefore makesure that the ambient temperature onthe pressure transmitter does not ex-ceed the max. specified value. In criti-cal applications, the use of a coolingelement or a capillary must be takeninto consideration.

The application temperatures are lim-ited by the max. permissible ambienttemperature of the pressure transmit-ter (85°C) as well as the different ther-mal characteristics of the isolatingliquids.

In addition, take into considerationthat when pressures below 1 barabs

occur, the isolating liquids boil evenat low temperatures. The followinglimit values result thereof:
