IECEx Approved Thermocouples

with Spring Loaded Terminal Block

These semi rigid IECEx approved thermocouples are supplied with a spring loaded terminal block and can be used to replace an insert in an existing application. They can be used with service temperatures up to 1250ºC (minimum stand-off lengths must be observed).
  • Available in a wide range of protection concepts for Zones 0, 1 & 2 use. See table below for details
  • Temperature classification T6-T1, see here for stand-off requirements
  • Available in thermocouple types K, T, J, N, E, R, S and B
  • Sheath diameters from 3.0mm to 8.0mm in a wide choice of materials
  • Insulated measuring junction gives a floating output with high insulation resistance
  • UKAS calibration available.
Available with the following approvals:

Protection Type Description Zone
Ex nA IIC Gc Non-Sparking (Gas) 2
Ex ia IIC Ga / IIIC Da Intrinsically Safe (Gas/Dust) 0/20
