General Purpose Thermocouples

Bolt (Nozzle) Thermocouple (Type 4)

Suitable for extruder nozzle, motor and pipe temperatures etc., these assemblies are available as standard in thermocouple types K, T, J, N and E. They can be supplied mounted into any bolt as required by the application and are available both as a fixed or a rotating bolt. They are supplied with either Stainless Steel braided Fibrgelass cable, which can be fitted with an anti-chafe spring if required, or alternatively, for more arduous applications, they can be supplied with Fibreglass cable inside a flexible Stainless Steel conduit (armour). Generally suitable up to 235°C depending upon the bolt used. Thermocouple junctions are grounded to the bolt as standard but can be insulated if required. We also welcome receiving your free issued bolts for manufacturing into a completed sensor.

Temperature ranges refer to the thermocouple type.
The temperature range of the sensor may deviate from the above,
please refer to the product description for more details

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

GROUNDED
Hot junction welded to sheath tip giving earthed output and faster response to temperature changes
