ATEX Approved Thermocouples

with Termination Entry Gland and Fixed Process Thread

Our ATEX approved mineral insulated thermocouple assemblies are manufactured from cable that conforms to IEC 61515 and their semi rigid construction allows them to be bent and formed to suit particular applications without impairing performance.

  • Temperature classification T6-T1, see here for stand-off requirements
  • Available in thermocouple types K, T, J, N, E, R, S and B
  • Sheath diameters from 1.0mm to 8.0mm in a wide choice of materials
  • Insulated measuring junction gives a floating output with high insulation resistance
  • Terminated in a compression gland pot seal with 50mm PTFE sleeved tails
  • UKAS calibration available.
Available with the following approvals:

INSULATED
Hot junction insulated from sheath. Gives floating output with typical insulation resistance in excess of 100 megohms


Assemblies with pot seals are supplied with short tails as shown. However, where leads are several metres or more long, it is more suitable to have an overall sheathed cable. We recommend the following cables.
