Dial Thermometers by WIKA - market leader since 1946

Our dial thermometers work on the bimetal, expansion or gas actuation principle. This enables scale ranges of -200 ... +700 °C (-328 ... 1,292 °F) 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 the factors influencing the response times of thermowells?

Put simply, one can say that the more stable a thermowell is constructed, the slower it reacts to temperature changes. In order to optimise the response time, there are thin wall thicknesses and low air space between sensor and the bore's interior walls. Further op ... More

How does a gas actuated thermometer operate?

The measuring system of the dial thermometer consists of a stem, capillary and Bourdon tube in the casing. These parts are combined to form a single unit. The entire measuring system is filled with an inert gas under pressure. A change in temperature will caus ... More
