Loop calibration with a
temperature transmitter at the bench
In industrial process industries, temperature
measurement equipment usually has two
components: a sensing device such as an RTD or
thermocouple and a transmitter to read and relay
the signal to the control system.
All sensors, including RTDs, drift with time.
Thus, testing the transmitter and not the sensor
could result in misjudgment regarding a system's
performance. To avoid this potential problem,
process instrument manufacturers recommend
including the temperature sensor in loop
calibration to prove the effectiveness of the
entire system.
