Dial thermometers

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 is the Hall effect?

If a constant current is running through a semiconductor component, and this component is then placed in a magnetic field, then a voltage (Hall voltage) is generated within this semiconductor component which is proportional to the strength of the magnetic field.

How does a bimetal thermometer work?

A strip made from permanently-laminated rolled sheets, made from metals having different coefficients of expansion ("bimetal"), will bend as a result of any temperature changes. The bending is roughly proportional to the change in temperature. For bimetallic strips ... More
