Also available with IECEx Approval Also available with EAC Ex Approval

Our ATEX approved flexible mineral insulated RTD Pt100 sensors 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. This sensor has a spring loaded terminal block which can be used for an existing assembly as a replacement insert.

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 3.0mm to 8.0mm
Wide operating temperature range of -100°C to +600°C
UKAS calibration available.

Available with the following approvals:

Protection Type	Description	Zone
