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

Does the ambient temperature have any influence on the measuring tube within the case of the gas-actuated instrument?

Yes, that is why a bimetal compensation is installed between the movement and the measuring tube. This compensation is technically limited within a specific range. For WIKA gas-actuated instruments the standard ambient temperature is approx. 23 ± 10 °C. ... More

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.
