Our dial thermometers work on the bimetal, expansion or gas actuation principle. This enables scale ranges of -200 to +700 °C in different class accuracies, response times and resilience to environmental influences. Diverse connection designs, stem diameters and individual stem lengths enable a flexible measuring point design. Dial thermometers with capillaries are particularly versatile. All thermometers are suited for operation in a thermowell if necessary.

FAQ

What are suitable materials for thermowells for negative temperatures?

The first choice for high-temperature applications should always be stainless steel, such as 1.4404 or 316L. (Approval per AD2000 W10 down to -270 °C) Carbon steels should be considered carefully in detail, through the effect of the drop-off effect.

When does one use a gas actuated thermometer with capillary?

Gas-actuated or expansion thermometers with capillaries are used in locations which are not easily accessible and where long distances have to be bridged. As a protective coating for capillaries, a flexible spiral protective sleeve or PVC coating is available.
