Type R Loops - Weldable

We manufacture these Type R thermocouple feedthroughs to transfer a thermocouple’s EMF through a vacuum chamber wall to a device. Rated for high and ultrahigh vacuum applications (depending on mounting termination).

Type R Thermocouple Feedthroughs Feature:

  • Feature positive wires made of Copper and negative wires made of Alloy 11 (Type R extension grade wires)
  • Temperature range from 0° C to 1,540° C
  • Both air-side and vacuum-side terminate in loops and include a stainless steel nut and screw to facilitate thermocouple attachment

Notes:
  • Because both Type R and Type S thermocouples use identical extension grade wires, Type R feedthroughs can also be used for Type S.
  • The electrical and thermal ratings specified are of safe operating limits determined by various factors including material properties, mechanical design, and the intended operating environment. All electrical ratings are based on operation with one side in dry atmosphere and the other side in vacuum of less than 1 x 10-4 Torr. All VacuCAD files as well as any dimensions shown or listed in our ordering tables do not include manufacturing tolerances and are provided for reference only.
