Verification Method of Thermocouple and Thermal Resistance Integrated Temperature Transmitter
Integrated temperature transmitter, mainly thermocouple and thermal resistance of two types. Before using, we need to detect the integrated temperature transmitter, can be unnecessary fault and error excluded. For the following to introduce the thermocouple and thermal resistance integrated temperature transmitter calibration method.
First, the thermocouple integrated temperature transmitter calibration method:
1, equipment requirements: a digital voltmeter;
2, according to the system connection method wiring;
3, according to the range of ten equal points input the potential value, check the temperature output is consistent with the accuracy range;
4, according to the transmitter nameplate on the sensor and range specified, enter the corresponding resistance, so that the output were 1V and 5V (adjustable zero potentiometer and full potentiometer);
5, according to the manual technical indicators to test, should meet the technical requirements.
Second, the thermal resistance integrated temperature transmitter calibration method:
1, equipment requirements: a digital voltmeter;
2, according to the range of ten equal points input the resistance value, check whether the temperature output to meet the accuracy range;
3, according to the transmitter nameplate on the sensor and range specified, enter the corresponding resistance, so that the output is 1V and 5V (can be adjusted zero potentiometer and full potentiometer);
4, according to the manual technical indicators to test, should meet the technical requirements.
