Thermocouple Inserts and Elements

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.

Common options include:

If you are unsure exactly what you need, get in touch and we can help identify your requirements.

Thermocouple Insert with Block

Very inexpensive sensor with block attached for quick replacement on plants.

Thermocouple Insert with DIN Plate

Cost effective sensor with industry standard plate which can affix your own transmitters or terminal blocks.

Thermocouple Insert with Transmitter

For insertion into an existing thermowell assembly where a transmitter will be fitted too.

Special Insert Options

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

  • Calibration

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

  • Material Certificates

    Material certificates are available on request.

  • Spring Loaded

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

  • Thermocouple Junction

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

  • Process Fittings

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

  • Duplex

    Thermocouples can be supplied duplex instead of simplex.

  • Tagging

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

  • Reduced tip options

    Reduced hot junction for fast response or cost saving.

Thermocouple Elements

As well as full thermocouples we can supply basic thermocouple elements either uninsulated or insulated for further assembly into sheaths or equipment.

Common options include:

Basic Thermocouple Wire Element

Replacement elements supplied uninsulated  for further assembly into sheaths or equipment. Can be supplied as separate spooled wires without junction.

Basic Thermocouple Insulated Element

Replacement elements insulated in ceramic for further assembly into sheaths or equipment.

Basic Thermocouple Insulated Wire Element

Replacement elements insulated in plastics or glass fibre for further assembly into sheaths or equipment.

Special Element Options

Our thermocouple elements have a number of options available including:

  • Individual Wires

    Elements can be supplied as separate spooled wires without a junction.

  • Material Certificates

    Material certificates are available on request.

  • Calibration

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

  • Cable Twisted/Untwisted

    Insulated cable can be twisted or untwisted pair.

  • Extra Ceramics

    Ceramic insulators can be purchased separately as well as part of an element.

  • Fish Spine Beads

    Ceramics can be purchased as fish spine beads rather than lengths of insulator.
