Electric couple thermometers consist of two metal conductors of different materials, which, under the effect of temperature, generate an electromotive force. This consequently produces an electric current whose intensity is directly proportional to the temperature difference between the two junctions. We can supply thermocouples K, L, J, T, R, S; all standardised by the international standard IEC 60584. The conductors are usually encased in a protective sheath in order to withstand the industrial environments in which it is installed better and longer. traditional insulation, generally consisting of ceramic insulators mineral oxide insulation innovative magnesium oxide insulation.
