Temperature transmitter is a kind of instrument, in the industry, chemical industry, agriculture, electricity, oil, machine tool, ship, etc are very important. Resistance temperature transmitter of them in the process of using are need to check, calibration requires users to pay attention to the problem is more, if the right way not only the accuracy of the measurement is reduced, also can cause resistance temperature transmitter damage problem, engineering today is to introduce for everybody resistance temperature transmitter calibration method.

1, calibration instrument:

( 1) R1, r2, r3 for RX - 11 - 6 - 14 w1 ohm resistance.

　　( 2) The voltmeter is 0. Level 1 dc five digital voltmeter.

milliammeter to 0. Level 1 0 20 ma dc milliammeter.

replace resistance Rt with precision dc resistance box.

2, calibration method and requirements: after check the wiring and correct, continuous electricity meter after 30 minutes, check.

stability check. Instrument calibration qualified, but also in the continuous work after four hours, to check the performance, conform to the technical standards, can input system.

more high quality thermocouple sensor from

key words: thermal resistance, thermocouple, thermal resistance, platinum resistance, PT100, PT1000, pressure thermocouple sensor, digital temperature thermocouple sensor
