The technology of temperature transmitters has become very mature and is very common in various factories. Temperature transmitters are often used in conjunction with some instruments, and there are often small malfunctions during the use of these instruments. The common faults and solutions are as follows.
Firstly, when the temperature of the tested medium increases or decreases, the output of the transmitter does not change. This situation is mostly due to the sealing problem of the temperature transmitter, which may be due to the temperature transmitter not being sealed properly or accidentally welding a small hole in the sensor during welding. This situation usually requires replacing the transmitter casing to solve.
Secondly, the output signal is unstable, which is due to the temperature source function. The temperature source function is an unstable temperature. If the instrument display is unstable, it is due to the weak anti-interference ability of the instrument.
Thirdly, the output error of the transmitter is large, and there are many reasons for this situation. It may be due to the incorrect resistance wire of the selected temperature transmitter causing range errors, or it may be due to the transmitter not being calibrated properly when it leaves the factory.
