Industrial Vacuum Furnace Thermocouple

These thermocouples are used in industrial vacuum furnaces up to at least 5 x 10-⁶ torr (6.67 x 10-⁶ mbar) where temperature up to 1600°C are experienced with a typical leak rate for better than or equal to 1 x 10-⁶ scc/sec. under 1 Atm. He @ 20ºC. (1 Atm. = 1.013 x 10⁴ Pa or 1013 mbar). Available in thermocouple types K and N with an impervious aluminous porcelain sheath or thermocouple types R and S with an impervious recrystallised alumina sheath, they have a stainless steel support tube attached to a weatherproof connection head. The sensor can then be inserted into the application with a vacuum tight sealing assembly (ref 940-161) which can be purchased separately. Please see the sealing assembly section on this website for more detailed specifications of the sealing assemblies. Whilst we offer a standard range of vacuum furnace thermocouples, due to the specialist nature of these sensors a full custom built service is available for both end users and OEM's.
