  • Mineral insulated thermocouple sensors have a high integrity construction, suited to arduous operating conditions at temperatures from -200ºC to +1400ºC. (The maximum operating temperature is dependant on diameter and environmental factors, further guidance is available here.)
  • 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

  • Rugged large diameter whilst a low thermal mass reduced tip provides a fast response
  • The process of swaging increases the strength of the sheath by enhancing the grain structure during forming
  • Available in thermocouple types K, T, J, N, E, R, S & B in lengths from a few millimetres to 200 metres or more 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 600ºC

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.
