thermocoupleIt is a commonly used temperature measuring element in temperature measuring instruments, which directly measures temperature and converts the temperature signal into a thermoelectric potential signal, which is then converted into the temperature of the measured medium through electrical instruments (secondary instruments); The following factors need to be considered when selecting thermocouples:

1. Temperature range to be measured;

2. Required response time;

3. Connection point type;

4. The chemical corrosion resistance of thermocouple or sheath materials;

5. Anti wear or anti vibration ability;

6. Installation and restriction requirements, etc.
