Thermometers of this product range find their application whenever a local temperature display is needed at the same time as switching an electric circuit.

Expansion thermometers can be installed or mounted in almost any location. Versions with capillaries are used in locations which are not easily accessible and where long distances have to be bridged. They can therefore be used universally, e.g. in machine building, refrigeration and air-conditioning applications or other industrial applications.

The case, capillary, stem and process connection are made from stainless steel. To optimise the fitting to the measuring location, different insertion lengths and process connections are available
