How is a thermocouple made
Web20 aug. 2024 · Simply put, a thermocouple is an electronic device which has two electrodes which are dissimilar in nature, with electrical junctions that form at different temperatures. Thermocouples are made of two different metal wires, and it is the difference in wire properties that forms the different junctions—with thermocouples typically having a hot ... WebWorking principle of thermocouples. When two wires composed of dissimilar metals are joined at both ends and one of the ends is heated, there is a continuous current which flows in the …
