ATEX / IECEx Approved RTD Pt100 Sensors

with Pot Seal

Our ATEX / IECEx approved flexible mineral insulated platinum resistance thermometers utilise, as standard, detector elements with a resistance of 100 ohms @ 0°C and a fundamental interval of 38.5 ohms to IEC 60751. Single and duplex elements are available. An adjustable threaded compression fitting is required to achieve approval.
  • 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 B, A, 1/3, 1/5 and 1/10 grade accuracies
  • Sheath diameters from 0.125" to 0.313"
  • PVC or PFA insulated extension cables are available or 100mm tails
  • Wide operating temperature range of -148°F to +1112°F
  • UKAS calibration available.
Available with the following approvals:

Wiring Diagram Sheath Materials

Assemblies with pot seals are supplied with short tails as shown. However, where leads are several metres or more long, it is more suitable to have an overall sheathed cable. We recommend the following cables.
