Thermocouple/heat resistance temperature transmitter calibration method

Thermocouple/heat resistance temperature transmitter calibration method

a, thermocouple temperature transducer calibration methods:

1. Equipment requirements: a digital voltmeter;

2。 According to the system wiring connection method;

3。 According to the transmitter range of sensors and range indicated on the nameplate, input resistance, make the output of 1 v and 5 v (respectively Can be adjusted respectively zero potentiometer and full potentiometer) ；

4。 According to the range of ten equinoctial input, such as the electric potential value, check whether the temperature output precision scope;

5。 According to the technical index test specification, and shall comply with technical requirements. ,
