Thermocouple units are used for sensing high temperatures as in furnaces, kilns, ovens etc. These devices use the principle of generating electricity by heating two dissimilar metal junctions. According to the principle, when two dissimilar metals are heated at their junction, electricity begins flowing across their opposite open ends.
