Resistance Thermometer Inserts and Elements

Resistance Thermometer Inserts

Resistance Thermometer Inserts are commonly used in pocket, thermowell or head assemblies. They are constructed with Pt100 sensors insulated and protected by mineral insulated powder, which is then packed inside a rigid metal tube. They are very similar to mineral insulated resistance thermometers 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.

Resistance Thermometer Insert with Block

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

Resistance Thermometer Insert with DIN Plate

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

Resistance Thermometer Insert with Transmitter

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

Resistance Thermometer Insert with Head

Usually supplied with a connection block in the head, although customers are able to fit an existing transmitter if specified.

Special Insert Options

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

  • Element Options

    Pt100 B as standard with Pt100 A, 1/3,1/5,1/10 DIN, Pt 50, Pt 500, Pt 1000 and Pt 2000 available on request.

  • 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.

  • Wire Configuration

    3 wire as standard, marked red/red/white, with 2 or 4 wires on request.

  • Process Fittings

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

  • Duplex

    Resistance thermometers 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.

Resistance Thermometer Elements

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

Common options include:

Basic Resistance Thermometer Element

Replacement elements supplied uninsulated  for further assembly into sheaths or equipment.

Basic Resistance Thermometer Insulated Element

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

Basic Resistance Thermometer Insulated Wire Element

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

Special Element Options

Our resistance thermometer elements have a number of options available including:

  • 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.

  • Extra Ceramics

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