In this article, we provide you the basic Instrument Calibration Questions on transmitters like pressure, transmitter, level and differential pressure transmitter.

Instrument Calibration Questions

Question 1:

Suppose you wish to calibrate an electronic pressure transmitter to an input range of 0 to 50 inches of water, with an output range of 4 to 20 mA. Complete the following calibration table showing the proper test pressures and the ideal output signal levels at those pressures:

Pressure Transmitter Percent of Span Error

Question 2:

An electronic pressure transmitter has a calibrated range of 0 to 200 inches of mercury, and its output signal range is 4 to 20 mA. Complete the following table of values for this transmitter, assuming perfect calibration (no error):

Question 3:

An electronic level transmitter has a calibrated range of 0 to 2 feet, and its output signal range is 4 to 20 mA. Complete the following table of values for this transmitter, assuming perfect calibration (no error).

Level Transmitter Percent of Span

Question 4:

A pneumatic differential pressure transmitter has a calibrated range of −100 to +100 inches of water column (” W.C.), and its output signal range is 3 to 15 PSI.

Complete the following table of values for this transmitter, assuming perfect calibration (no error).

Differential Pressure Transmitter Percent of Span Error

Question 5:

Suppose you wish to calibrate an RTD temperature transmitter to an input range of 50 to 200 degrees F, with an output range of 4 to 20 mA.

Complete the following calibration table showing the proper test temperatures and the ideal output signals at those levels:
