Screw in resistance thermometers with sheath measurement inserts

Resistance thermometers with threaded socket and mineral-insulated gauge slide (55-WES) are used for general temperature measurement in low-pressure gaseous, liquid and plastic media environments, depending on the properties of the protective tube and surrounding media, up to a temperature of 800°C.


A threaded socket is welded to the protective tube, providing for the stability of the process connector in sensors of this product line. Depending on the application, the socket is welded to the protective pipe, either directly beneath the connection head or with a gap of 100 or 200mm, for example.

The protective fittings are usually made from a single seamlessly drawn high-grade steel tube with a circular blank welded inside.

In order to facilitate particularly quick temperature change measurements, we offer sensors with a tapered sensor tip.

For specialised applications (precision, long-term stability, etc.) we recommend the application of precision resistors with narrowed tolerance.
Resistance values and tolerances of our resistance thermometers are pursuant to DIN EN 60751.

Our resistance thermometers are also available in explosion protected ATEX models.
