Other Information

Thermocouple feedthroughs do not measure temperature, but merely provide a conduit to bring the EMF signal generated at a thermocouple junction through a vacuum vessel wall to an external voltage measuring or temperature readout instrument. Type-K thermocouples with positive Chromel wires and negative Alumel wires are recommended for use in clean oxidizing atmospheres. The maximum operating temperature for these alloys is 1260 C for larger wire sizes. The useful temperature measuring range for a Type-K thermocouple is between (-)200 C to (+)1250 C.
