What is a thermocouple wire?

Chinese name
Thermocouple wire

English name thermocouple wire

Definition
The metal or alloy wire that constitutes the two hot electrodes of a thermocouple.

Manganese white copper with high manganese content can be used to make thermocouple wires. It is the core component of temperature sensors and cannot measure temperature itself. The principle is thermoelectric effect, which means that one end of two different metals are welded together. When the welding point is heated to a certain temperature, a significant potential will be generated at both ends. The voltage will be measured by a pressure measuring instrument and the temperature will be inferred
