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

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

What influence does the ambient temperature have on the measuring result?

This depends on the following parameters:
1. Ratio of the volume of the probe (tube) to the measuring line and Bourdon tube (rule-of-thumb: 99:1)
2. Length of the measuring line (capillary) - the longer it is, the more the influence
3. Magnitude of t ... More
