Temperature sensor
Thread Content
What are the types of faults in temperature sensors, and what are the troubleshooting methods?
If it’s intelligent, you just need to use a controller similar to the 475 or relevant communication software for diagnosis; the error codes, along with the accompanying instructions, will help determine the issue
Different sensors require different inspection methods: thermal resistors have their resistance value checked, while thermocouples have their mV value measured.......
I. Display issues 1. Excessively high display (1) Check whether the terminals are corroded. (2) Check if the connections are loose. 2. Excessively low display (1) Check for short circuits in the connections. (2) Check if water or conductive dust has entered the junction box. (3) Check the grounding of the circuit. II. No display 1. Check the connections. 2. Check for open circuits. 3. Check whether the sleeves are damaged
