Cermaseal: Thermocouple Feedthroughs

November 20, 2002
Ceramaseal's thermocouple feedthroughs transmit, through the wall of vacuum, pressure or controlled atmosphere chambers, the electromotive force (emf) generated by the application of heat to the thermocouple bead without introducing error. External instrumentation can then evaluate the strength of the emf that is proportional to the temperature at the thermocouple bead, yielding a temperature measurement. The company's thermocouple feedthroughs provide the necessary electrical isolation and a hermetic seal. New to the company's existing product offering are single thermocouple feedthroughs; three and five pair spade type thermocouples; and single- or double-ended circular connector thermocouples, which come in 1, 3, 5, 9, 16 or 20 thermocouple pairs.
