Part number:

Principle:
According to the Seebeck effect, when two different metals are combined there is touch voltage at the points of contact, which depends on the temperature.

The thermo material combinations are standardized. The different material properties of a thermocouple determine the different application cases.

The following table shows the assignment of thermocouple types to the various material compositions:

Note:
When you use thermocouples, you must run a temperature compensation. More information on the temperature compensation options when using thermocouples is available in Entry IDs: 19164525; 19163406; 19164641; 19243010
