  • High integrity construction suited to arduous operating conditions at temperatures from -330°F to 2300°F (-200ºC to +1250ºC). 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 spring loaded terminal block suitable for mounting into any standard terminal head. The ceramic terminal block has 2 x 1.30" spaced mounting holes. Suitable for simplex, duplex and triplex assemblies
  • 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 0.188" to 0.315" and lengths from a few inches to hundreds of feet 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 1110°F
