IECEx Approved Thermocouples for the Petrochemical, Oil and Gas Industries

with Stainless Steel Head and Fixed Process Thread

Supplied with an IP68 termainl head, these semi rigid IECEx approved thermocouples are ideal where a heavy duty connection with cable is to be made near the sensor. They are suitable for use with service temperatures up to 1250°C (minimum stand-off lengths must be observed).
  • The following thermocouple types are available: K, T, J, N, E, R, S and B
  • A wide range of protection concepts are available for use in Zones 0, 1 & 2. See table below for details
  • For stand-off requirements (Temperature classification T6-T1), see here
  • Sensors are available in either Simplex, Duplex or Triplex
  • Available in 4.5mm, 6.0mm or 8.0mm in a wide variety of sheath materials
  • These products can be UKAS calibrated
  • A floating output with high insulation resistance is given via an insulated measuring junction
Available with the following approvals:

Protection Type Description Zone
Ex nA IIC Gc Non-Sparking (Gas) 2
Ex d IIC Gb Flameproof (Gas) 1
Ex ia IIC Ga / IIIC Da Intrinsically Safe (Gas/Dust) 0/20
Ex tb IIIC Db Enclosure (Dust) 21
Ex tc IIIC Dc Enclosure (Dust) 22
