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 mechanical influences, other than the actuation of switch contacts, can cause measuring errors in bimetal thermometers?

In helical bimetal spring designs, a stroke movement of the pointer may occur, which may lead to the pointer touching on the dial or the window.  With the assistance of modern design and manufacturing techniques, such errors are avoided nowadays.

When are one-piece or fabricated thermowells typically used?

Fabricated thermowells are generally recommended for low to medium process loads. One-piece  thermowells are suited to the highest process loads, depending on their design. Thus internationally or in the petrochemical industry, one-piece thermocouples are now ... More
