Heinz Introduction：The H. Heinz Meßwiderstände GmbH was established on 1 April 1991 in Elgersburg, Thuringia. Initially, only sensor resistors were fabricated. According to the market trends the production spectrum has been extended continuously. Consequently, Pt 100 temperature sensors, thermocouples, resistance thermometers, mineral insulated resistance thermometers, foil sensor resistors, silicone sensor resistors, and average value sensors have been developed and fabricated.
