Miniature Thermocouples with Miniature Jack

Miniature Thermocouple - Miniature Thermocouple with Miniature Jack

  • 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 choice of miniature thermocouple jacks rated to 425°F, 660°F or 1200°F (220ºC, 350ºC or 650ºC)
  • 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 with sheath diameters from 0.010" to 0.040" and lengths from a few inches to hundreds of feet dependent on the sheath diameter selected
  • See detailed information on how a thermocouple works

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
