With the advancement of technology and the development of sensor technology, the application of terminal sensor in various fields has become more and more common. Although sensor manufacturers have various strict internal quality control procedures and procedures, the existence of errors is reasonable, so some problems or malfunctions may occur when temperature sensors are applied. Having a certain common sense of temperature sensor troubleshooting is also one of the necessary skills. Let's share some common faults and solutions in temperature sensor applications.

First, the output of the transmitter does not change when the temperature of the measured medium rises or falls. This situation is mostly a temperature sensor sealing problem, which may be because the terminal sensor is not sealed well or the sensor is accidentally welded during welding. A small hole, this situation generally needs to replace the sensor shell to solve.

Second, the output signal is unstable. This reason is the temperature source's ability. The temperature source's ability is an unstable temperature. If the display of the meter is unstable, it is the reason that the anti-interference ability of the meter is not strong.

Third, the output error of the transmitter is large. There are many reasons for this situation. It may be that the resistance wire of the selected temperature sensor is wrong, which leads to the wrong range. It may also be that the sensor is not calibrated when it leaves the factory.

It is rare for the temperature sensor to fail. As long as it is carefully tested when leaving the factory, these conditions can be avoided. Therefore, the temperature sensor must be tested at one place when it leaves the factory. Customers can also ask the sensor manufacturer for a factory test report. Make reference
