Mineral Insulated Thermocouple Extensions

Thermocouple Extensions with Cable or Connectors

  • Steel sheathed mineral Insulated thermocouple extension cables
  • High integrity construction suited to arduous operating conditions at temperatures from -200°C to +1250°C
  • High insulation resistance
  • The cable used to manufacture these assemblies conforms to BS EN 61515: 2016 / IEC 61515: 2016 and BS EN 60584 class 2, other tolerances are available on request
  • Available in K, T, J and, N with sheath diameters from 1.5mm to 6.35mm and lengths from a few millimetres to 200 metres or more dependent on the sheath diameter selected
  • Sheaths can generally be bent, twisted and flattened to suit particular installations without impairing performance
  • Available with either pot seal terminations (with tails or cable) or with a choice of connector terminations

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, which are 7/0.2mm, laid flat and overall sheathed constructions. Other cables are available, please contact us for details.
