Conventional Bare Wire Thermocouples

Conventional Bare Wire Thermocouples are manufactured from two wires of dissimilar metals while being insulated with ceramic bored insulation beads.

The T1 and T2 element construction can be traced back to the origins of thermocouple history.

Our Conventional Bare Wire Thermocouples are suitable for general temperature measurement as well as heat treatment uses.
We can supply these in a variety of thermocouple types, wire diameter sizes and are also customisable to our customers individual industrial requirements as elements or as fully constructed assemblies.


  • Available as type J, K, N T & E
  • Available as type R, S & B with recrystallised Alumina ceramic beads
  • Ceramic Insulation beads available as twin bore as standard but 4 bores are also available
  • Exposed hot end junction
  • For use up to temperatures of 1100 °C

Optional thermal calibration is also available in our fully automated, UKAS accredited thermal calibration laboratory (No. 0600) (ISO 17025).
The CCPI Europe Calibration laboratory operates in the temperature range of –200 °C up to and including 1600 °C. It also proudly holds some of the tightest uncertainties of measurement for thermal calibrations held by a commercial calibration laboratory.
