Thermocouple - Type-K Vacuum

Thermocouple / Power hermetic subminiature-D feedthroughs are mixed thermocouple-power contact combinations fitted on one feedthrough assembly constructed with pin arrangements designed to meet IEC 807-2 and DESC 85039 specifications.

Standard configurations include power pins, Chromel® / Alumel® Type-K thermocouple pin pairs and combinations in a single subminiature-D shell.  Straight through pins are hermetically sealed and electrically insulated in a stainless steel shell using the latest in glass-ceramic bonding technology.  Ultrahigh vacuum cable assemblies with PEEK (polyetheretherketone) connectors and Kapton® insulated wires are available to meet the demands of UHV environments.  Vacuum side cable assemblies, individual connectors, and other accessories are available from the links below.  Custom thermocouple-power feedthrough flange and cable assemblies are available on request.

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.
