What causes damage to the temperature transmitter? For example, two-wire PT100 integrated temperature transmission

1. When there are obvious circuit connection problems, such as turning the power supply 24V into 220V; 2. The internal component circuit board is damaged when the transmitter is bumped or other hard collisions; 3. There is a problem with the PT100 itself; 4. The operating environment The temperature should not be neglected! The temperature change of SITRANSTH100 used in combination with PT100 will cause the transmitter to be permanent when the temperature is higher than 85°C. 1.

In addition, TH100 protection grade; IP40 terminal IP00 of the shell should be sealed when installed on site. TH100 cannot be compared with TH200. It has no diagnostic function. Generally, it is difficult to confirm what caused the damage
