Our EAC Ex mineral insulated thermocouple assemblies are manufactured from cable that conforms to IEC 61515 and their semi rigid construction allows them to be bent and formed to suit particular applications without impairing performance. 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 thermocouple types K, T, J, N, E, R, S and B
Metrological / Pattern Approval Certificate (PAC) for Russia also available on request, contact us for details
Additional Primary verification “POVERKA” available on request, contact us for a quotation if required

Sheath diameters from 0.5mm to 8.0mm in a wide choice of materials
Insulated measuring junction gives a floating output with high insulation resistance
PVC or PFA insulated twisted extension cables. Other cables available.
UKAS calibration available.

Available with the following approvals:

INSULATED
Hot junction insulated from sheath. Gives floating output with typical insulation resistance in excess of 100 megohms

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.
