   Description
    Thermometers of this product range find their application whenever a local temperature display is needed at the same time as switching an electrical circuit.
    Expansion thermometers can be fitted into or onto almost any point. 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 in just about any application; such as in machine building, refrigeration and air-conditioning technology and other industrial applications.
    The case, capillary, stem and process connection are made from stainless steel. To optimise the fitting to the measuring point, different insertion lengths and process connections are available.
