Dial thermometers

Dial thermometers with scale ranges from -200 to +700 °C

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 location design. Dial thermometers with remote 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.
