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

How can one prevent the zero position of the thermometer which has already been set during the manufacturing process, from altering (drifting) in later use?

Such a drift can be anticipated through suitable heat treatment (ageing). The finished bimetallic springs, ready for installation, should be held at a temperature of 350 °C to 400 °C (if required, higher temperatures are also possible), but stabili ...
