The use of temperature transmitters and applications is very numerous and extensive, but there are many users who are very familiar with the maintenance and verification of temperature transmitters . Actually, there are many methods of temperature transmitter calibration and can be suitable for different Users of temperature transmitters are used in occasions. The following temperature transmitters are calibrated in five steps. Please refer to:
First, the requirements of the equipment, you need to prepare a digital voltmeter;
The second is to connect the system according to the method of connection;
The third is based on the temperature transmitter above the indicated sensor and range, enter the corresponding resistance, so that the output is 1V and 5V;
The fourth is to input each resistance value according to the ten division points of the measuring range, and check whether each temperature output meets the range of accuracy;
Fifth, the operating staff must test according to the specification of the specification, and should meet the relevant technical requirements.
The verification of the temperature transmitter is also performed by most people in two ways: A heating furnace can control the heating curve, directly with a thermal resistance or thermocouple inserted in the furnace inside the furnace, through the temperature Controlled temperature check output.
The other is no thermal resistance or thermocouple, buy a temperature verifier, analog thermocouple thermocouple signal can be connected to the temperature of the input, the output and display calibration.
