Dial thermometers

Dial thermometers with scale ranges from -200 to +700 °C

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 location design. Dial thermometers with remote capillaries are particularly versatile. All thermometers are suited for operation in a thermowell if necessary.

FAQ

Why is the bending on temperature rises not linear over the entire temperature range?

Since the specific thermal expansion coefficient of the bimetallic components is temperature dependent.
