Mineral Insulated Thermocouples

with 316 Stainless Steel head

  • High integrity construction suited to arduous operating conditions at temperatures from -200ºC to +1400ºC (dependent on sheath material and thermocouple type)
  • Custom built to your specification and terminated in a weatherproof 316 Stainless Steel, screw top terminal head with the tube entry and cable entry at a right angle to each other, with a ceramic terminal block. Suitable for simplex and duplex assemblies. Supplied with a 20mm x 1.5mm ISO metal pinch gland on the cable entry for cables from 6mm to 14mm diameter
  • 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 4.5mm to 8.0mm and lengths from a few millimetres to 200 metres or more dependent on the sheath diameter selected

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 300ºC
