Base Metal Thermocouple Inserts

Special Options

All our thermocouples are custom made, as such we are able to tailor your sensors exactly to your requirements. There are many extra options available including:


Full UKAS or UKAS traceable calibration is available. AMS 2750 F to full or traceable calibration is available.

Process Fittings

Flange or compression fittings can be added such as an adjustable or welded flange on shank.

Material Certificates

Material certificates are available on request.


Thermocouples can be supplied duplex instead of simplex.

Spring Loaded

The design can be spring loaded to give a good thermal contact with pocket/thermowell.


Your own serial, product number or other information attached to sensors via heat shrink cable or metal tags.

Thermocouple Junction

Thermocouple junctions can be insulated, exposed or grounded depending on what’s suitable for your application.

Reduced tip options

Reduced hot junction for fast response or cost saving.

Thermocouple Inserts

Thermocouple Inserts are commonly used in pocket, thermowell or head assemblies. They are constructed with thermocouple elements insulated and protected by mineral insulated powder, which is then packed inside a rigid metal tube. They are very similar to mineral insulated thermocouples but they cannot be bent to shape.
