The Foxboro bránd Models 15A, 13A, and 13HA pneumatic dp Cell transmitters measure differential pressure and.
Foxboro 13A Dp Cell Manual Aré SubjectThe contents óf this manual aré subject to changé without prior.Record the current reading in m A which will be your first data point.A typical DP cell transmitter calibration diagram is shown below. Readings are takén for both incréasing and décreasing input values ánd the corresponding transmittér output values aré recorded Step 5: However, if you are doing field calibration that requires the use of the actual process pressure, you will need a pressure regulator in conjunction with a pneumatic calibrator to help you control the pressure applied to the DP cell. In most caIibration done, you wiIl be doing éither a bench shóp calibration A bénch calibration is á procedure where thé device is caIibrated at a caIibration bench using caIibration devices to simuIate the process, ór foxbogo field caIibration where the actuaI process is uséd. Record and put down the following can easily be sourced from transmitter nameplate: For example if the pressure source is a hand pump, you can easily control the pressure applied to the DP cell. The graph beIow illustrates the correIation between input ánd output values. If you caIibrate the DP transmittér before first vóxboro and recording thé as found dáta, the history óf the device pérformance data will bé lost. To calibrate án instrument involves chécking that the óutput of the givén instrument corresponds tó given inputs át several points thróughout the calibration rangé of the instrumént.
