Temperature transmitter technology has been very mature, very common in the factory, the temperature transmitter is often used with some instruments, and there are often some small failures in the process of matching. Common faults and their solutions are as follows:

First, the transmitter output does not change when the temperature of the measured medium rises or falls, which is mostly a problem of the temperature transmitter seal, which may be due to the fact that the temperature transmitter is not sealed well or the sensor is accidentally welded into a small hole when welding, which generally requires the replacement of the transmitter housing to solve.

Second, the output signal is unstable, this reason is the reason for the temperature source, the temperature source is an unstable temperature, if the instrument display is unstable, it is the reason why the anti-interference ability of the instrument is not strong.

Third, the output error of the transmitter is large, and there are more reasons for this situation, which may be that the resistance wire of the selected temperature transmitter is not correct leading to the wrong range, and it can also be that the transmitter is not calibrated well when it is delivered.
