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

How high is the permissible pressure loading for thermowells?

In the Appendix to DIN 43772 are loading diagrams, from which, depending on temperature and medium, can be taken, the maximum allowable pressure load for the different geometries. If the conduit geometry does not correspond to DIN 43772, individual calculations can ... More
