Operating Precautions for Temperature Transmitters
Jun 21, 2022
The temperature transmitter technology has been very mature, and it is very common in various factories. The temperature transmitter is often used in conjunction with some instruments, and there are often some small faults during the supporting use. The more common faults and solutions are as follows.
First, the output of the transmitter does not change when the temperature of the measured medium increases or decreases. Most of these cases are caused by the sealing of the temperature transmitter. It may be because the temperature transmitter is not sealed well or is careless during welding. The sensor is welded with a small hole, which generally requires replacing the transmitter housing to solve.
Second, the output signal is unstable. This reason is the reason of the temperature source, which is an unstable temperature. If the instrument display is unstable, it is the reason that the anti-interference ability of the instrument is not strong.
Third, the output error of the transmitter is large, and there are many reasons for this situation. It may be that the resistance wire of the selected temperature transmitter is not correct, resulting in a wrong range, or it may be that the transmitter is not calibrated well when it leaves the factory.
