Mineral Insulated Thermocouples

with Pot Seal

  • High integrity construction suited to arduous operating conditions at temperatures from -330°F to 2300°F (-200ºC to +1250ºC)
  • Custom built to your specification and terminated in a wide choice of pot seal styles and temperature ratings. Supplied with either short tails as shown or a longer extension lead
  • Alternatively, we have a large range of sensors available to buy online in various diameters and lengths
  • High accuracy and stability maintained throughout the operating life of the sensor
  • Fast response and high insulation resistance
  • Available in thermocouple types K, T, J, N, E, R, S, B, C & D with sheath diameters from 0.010" to 0.50" and lengths from a few inches to hundreds of feet dependent on the sheath diameter selected

* 5.5mm diameter is a thick wall heavy duty construction

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

GROUNDED
Hot junction welded to sheath tip giving earthed output and faster response to temperature changes

EXPOSED
Fastest response mainly for the measurement of air temperature in ducts. Restricted to a maximum operating temperature of 570°F


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 Wire. We recommend the following Wires, which are 32 AWG, Parallel and overall sheathed constructions. Other Wires are available, please contact us for details.
