Thermo-Electra designs and produces thermocouples and uses heat-resistant steel and ceramic tubes for glass, metal, and brick making factories. Stainless steel-protected sensors are most used in laboratories, general machinery and the food industry, and vibration-resistant sensors for bearing measurements and diesel engines. Our thermocouples can be supplied with a certificate from Lloyds Register, Rina, Buro Veritas etc. Further, a complete line of sensors with standard "DIN" constructions are made with an interchangeable insert, for easy replacement. Also most of our thermocouples are available in ATEX or IECEx version for Exe, Exia, Exna/Exce, Exd, Extb for zones 0, 1, 2 and 20, 21, 22.
