Typical Pressure Applications

How to calibrate a P / I Transmitter

With a built-in hand pump, pre-cision measurement of bothpressure and current, and a 24volt loop supply, the Fluke 718Pressure Calibrator is a complete,self-contained tool for the cali-bration of P/I transmitters. Tocalibrate a 3-15 psi / 4-20 mAtransmitter using a Fluke 71830G Pressure Calibrator:1. Depressurize the transmitter,

and then plumb the transmit-ter to the 1/8 inch NPT pres-sure port of the 718. Connectthe test leads per the figurebelow.

2. Turn the calibrator on. (If youneed to power the transmitter,hold down the UNITS keywhile turning on the calibrator.)

6. Press the HOLD key, andrecord the psi and mA read-ings. Press the HOLD key toresume reading.

7. Calculate and record the error,using: Error = ([ (i-4)/16] –[(P-3)/12]) * 100 where Erroris in % of span, i is your mea-sured current in mA and P isyour measured pressure in psi.

8. Repeat steps 5 through 7 atmid-range, around 9 psi, tocheck linearity at mid-span.

9. Repeat steps 5 through 7, nowat 15 psi, for a check at 100 %of span.

If your calculated errors arewithin tolerance, the transmitterhas passed your As-found test,and you are done. If necessary,perform your zero and span ad-justments, then repeat steps 5through 9 for an As-left test.Depressurize the line, and dis-connect the 718.

Measuring less than 9 inchesin length and weighing just overtwo pounds, the rugged 718 iseasy to carry into the field. The718 is offered in both 30 psi and100 psi models. Media compat-ibility is dry air and non-corro-sive gasses. A built-in pumpgenerates pressure or vacuum.Min, Max, and Hold functions are

Sourcing pressureTo calibrate an instrument with pressure input, pressure froman external source (such as a hand-held pump) is applied.Prompts on the 740 Series Calibrator display indicate whento increase or decrease the input pressure, and when thespecified test points are achieved. Here, a Fluke 741B Docu-menting Process Calibrator is shown.

Measuring pressureTo measure pressure, the appropriate pressure module for thepressure to be tested is attached to the calibrator. The mea-sured pressure can be displayed in a variety of engineeringunits. Here, a Fluke 725 Multifunction Calibrator is shown.

P to I device calibrationThe P to I device is used to convert pneumatic analog loopcontrol signals of 3 psi to 15 psi to electrical loop analogcontrol signals of 4 mA to 20 mA. Here, a Fluke 716 PressureCalibrator is used.

Differential measurementsDifferential pressure modules are useful in a widevariety of applications, e.g., measuring the fluidlevel in a tank or calibrating a differential pressuretransmitter. A Fluke 744 Documenting ProcessCalibrator is shown.

I to P device calibrationThe I to P device is used to convert 4 mA to 20 mAelectrical analog loop control to pneumatic analogloop control, generally 3 psi to 15 psi. Here, atypical configuration for using a pressure modulewith a 740 Series DPC is demonstrated.

A complete family of pressuremodulesA family of 29 pressure modulescovers the most common pres-sure calibrations from 0-1" H2O(0-.25 kPa) to 0-10,000 psi(0-70,000 kPa).

Gage pressure modules haveone pressure fitting and measurethe process pressure with re-spect to atmospheric pressure.Differential pressure moduleshave two pressure fittings andmeasure the difference betweenthe applied pressure on the highfitting versus the low fitting.Each module is clearly labeledfor range, overpressure specifica-tion, and media compatibility. Ametric adapter is included withall but the P29 through P31 highpressure modules.

Quick and easy measurementsFluke 700 Series pressure mod-ules are easy to operate. To mea-sure pressure, the technicianplumbs the pressure module to apressure source, and connectsthe pressure module cable to thecalibrator. Pressure is applied,measured by the pressure mod-ule, and displayed digitally onthe calibrator. At the touch of abutton, the pressure may bedisplayed in up to 11 differentengineering units. When usedwith the 701, 702, 741, 743 or744 Documenting Process Cali-brators, pressure readings can bedate/time stamped and storedelectronically for later retrieval.This saves time, eliminateserrors, and supports compliancewith quality standards andregulations.

Pressure module performanceFluke 700 Series pressure mod-ules are highly accurate, withtotal specifications that applyfrom 0% to 100% of full span andfrom 0°C to 50°C (32°F to 122°F)—a feature that sets them apartfrom other pressure calibrators.Many ranges have total uncer-tainties of 0.05% of full scale andreference uncertainties of 0.025%of scale (see Table, page 5).

This performance is possiblethrough the innovative applica-tion of mathematics and micro-processor power. Fluke pressuremodules have silicon piezo-resistor sensors which consist ofa resistive bridge fabricated in asilicon diaphragm. Pressure ap-plied to the diaphragm causes achange in the balance of thebridge which is proportional tothe applied pressure. The bridgebalance change is not linear andis very sensitive to temperature.However, since these effects arequite stable with time andthrough repetitive changes ofcondition, the sensors can bevery accurate in measuring pres-sure provided they are carefullycharacterized.

During manufacture, Flukepressure modules are character-ized by reading temperature andpressure at more than 100 points.A least-squares regression isused to calculate the coefficientsof a polynomial expression forpressure. The coefficients, uniqueto that pressure module, arestored in the module’s memory.

Each module has its ownmicroprocessor, allowing it to runthe measurement circuitry and tocommunicate digitally with acalibrator. When connected to the

calibrator, the modules coeffi-cients are uploaded from thepressure module to the calibrator.Then, as pressure measurementsare made, raw sensor values forpressure and temperature aredigitally loaded to the calibrator,where the raw sensor values andcoefficients are manipulated toderive and display the pressurereading. This innovative tech-nique provides several benefits:1. Digital communication elimi-

nates errors due to poorconnections and electricalinterference.

2. The modules are inherentlytemperature-compensatedfrom 0°C to 50°C (32°F to122°F).

3. The modules are fully inter-changeable because allmeasurements are completedin the pressure module itselfand then communicated to thecalibrator in digitized form.Modules are calibrated inde-pendently of the calibrator,and can be used with any 700Series calibrator. Each modulehas its own serial number tofacilitate traceability.

Sensor protection inisolated modulesMany of these modules (seeTable) incorporate a stainlesssteel diaphragm to isolate thesensor. With these modules, anymedium that is compatible withstainless steel can be used onthe high side of the module.

Rugged constructionA urethane overmolding protectsagainst shock if a module is acci-dentally dropped and also sealsagainst dirt, dust, and moisture.Pressure connections are 1/4"NPT. A BSP/ISO adapter is alsoprovided on all but the P29, P30and P31.

Convenient setupA one-meter cable between thepressure module and calibratorreduces the length of connectingtubing to the pressure source.The remote pressure head alsoprovides an extra margin ofsafety and convenience by re-moving the calibrator and opera-tor from the pressure source.

Pressure Terminology

PSI—pounds per square inch(same as psig).

PSIA—pounds per square inchabsolute.

PSID—pounds per square inchdifferential.

PSIG—pounds per square inchgage (same as psi).

Square root extractor—aninstrument or software programthat takes the square root ofinput and puts the result on itsoutput. Square root extraction isneeded to linearize many flowsignals. Example: orifice plates,venturis, target flow meters, andpitot tubes all require thetransmitter’s output signal to belinearized. Mag flow meters,turbine flow meters, Dopplerflow meters, and vortex shed-ding flow meters don’t requiresquare root extraction.

Static pressure—the zero-veloc-ity pressure at any arbitrarypoint within a system.

Wet/dry differential—a differ-ential pressure transducer ortransmitter that uses a metaldiaphragm at the wet portwhere fluids can be applied, andno diaphragm at the dry port.The dry port exposes the sensormaterial to the medium, so onlyclean dry gas can be applied tothis port.

Wetted parts—the diaphragmand pressure port material thatcomes in direct contact with themedium (gas, liquid).

Gage pressure—the pressurerelative to atmospheric pressure.Gage pressure = absolute pres-sure minus one atmosphere.

Gage pressure transducer—a transducer that measures pres-sure relative to atmosphericpressure.

Ideal Gas Law—combiningBoyle’s Law and Charles’ Law,results in the Ideal Gas Law:PV=nRT, where nR is constantfor a particular gas analogous tothe number of molecules and therelative size of the molecule.

I/P (I to P)—a current to pres-sure transmitter. A common in-strument in modern industrialplants. A typical large paper millor refinery could have 5,000 I/Psin use.

Line pressure—the maximumpressure in the pressure vesselor pipe for differential pressuremeasurement.

Orifice plate—a very low costand common primary sensingelement (PSE) for measuringflow. It must be used in conjunc-tion with a d/p cell. It creates aventuri and a resulting P isdeveloped across the platewhose square root is propor-tional to flow.

P/I (P to I)—a pressure to cur-rent transducer.

Pneumatic relay—refers to apneumatic instrument that per-forms a function to its input andprovides the result on its output(Example: square root extractor,adder, etc.).

6 Fluke Corporation Pressure Calibration

Absolute pressure—absolutepressure measurements arereferenced to zero pressure,(a perfect vacuum.)

Absolute pressuretransducer—a transducer thathas an internal referencechamber sealed at or close tozero pressure (full vacuum)when exposed to atmospherea reading of approximately14.7 psi results.

Boyle’s Law—the volume of agas is inversely proportional tothe pressure of the gas at con-stant temperature: V=1/P.

Common mode pressure—theunderlying common pressure(or static pressure) within a sys-tem from which a differentialmeasurement is being made.

D/P: Differential pressure,(pronounced DP)—other namesused to mean the same thing ared/p cell, d/p transmitter and ∆Ptransmitter (where ∆ is delta ordifferential). This is the mostcommon type of transmitter usedin most process industries. It canbe used to measure level, flow,pressure, differential pressure,and density or specific gravity.With some modifications, it canmeasure such things as tempera-ture and oxygen purity. The d/ptransmitter can be pneumatic,electromechanical, or solid state.It can also be a smart transmitter.A typical large process plant canhave hundreds or thousands ofd/p transmitters in service.

• 1/8-BSP (ISO228) female par-allel thread fitting for the unitunder test

Note: The user must provide a hose withappropriate end fittings from this port tothe unit under test.

Application: This pump canprovide up to 10,000 psi usingdistilled water or mineral-basedhydraulic oil. The pump is oper-ated by pumping several strokesto prime the system, thenswitching to high pressure modewhen the resistanceincreases. An integral pressureadjustment vernier knob variesthe pressurized volume by0.6 cc. The pressure variationachievable with the vernier willdepend on the nominal pressureand total pressurized volume,but with a minimum volume, the

vernier provided 150-3,000 psi(at 150 psi nominal) and 3,000-10,000 psi (at 3,000 psi nomi-nal) adjustment ranges. With aminimum volume andno pressure applied, the verniercan also be used to provide a0 to 1.7 psi range. Largervolumes will provide a smallerrange of adjustment, but greaterresolution.Included:1. Adapter to connect the

reference gauge port on thepump body to the 1/4 NPTmale fitting on Fluke 700PxxPressure Modules (except700P29, P30, and P31)

2. Adapter to connect thereference gauge port on thepump body to the 1/4 NPTfemale fitting on the Fluke700P29, P30, and P31Pressure Modules
