Temperature Sensors

Thermocouple wires manufactured by Johnson Matthey use the highest grade and purity of platinum and platinum group metal alloys to suit type R, S and B thermocouples. They are tested against international standards, thus guaranteeing optimum performance and tolerance limits.

Thermocouple: Single Wires


Common diameters of 0.5mm and 0.35mm and lengths for single thermocouple wires are available ex-stock for immediate delivery. Other diameters are available on request.

  • TC WIRE Pt
  • TC WIRE 10%Rh/Pt
  • TC WIRE 13%Rh/Pt
  • TC WIRE 6%Rh/Pt
  • TC WIRE 30%Rh/Pt

Thermocouple: Special Requirements

Specifications can be tailor-made to suit customer requirements including:

  • calibration details
  • physical properties such as elongation (%), breaking load (g) and UTS (N/mm2)
  • single or double wires on one reel with hot junction formed
  • security coding for deterrent of theft
  • fine thermocouple wired down to 40 micron
  • metal clad thermocouples, consisting of thermocouple wires embedded in an insulating refractory material surrounded by a seamless protective metal sheath.

Thermocouple: Refining

Customised precious metal recovery and refining packages are available upon request.
