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 point design. Dial thermometers with capillaries are particularly versatile. All thermometers are suited for operation in a thermowell if necessary.

FAQ

What is the maximum length of a capillary for gas actuated thermometers?

Theoretically, the capillary of a gas-actuated thermometer can be up to 100 m long. However, a large probe volume is needed so that the gas-actuated thermometer will operate within class 1. With the expansion thermometer, the maximum length is limited to 15 metres, ... More

How does an expansion thermometer work?

The measured value registration is made through the liquid-filled measuring system which consists of a temperature probe, capillary and Bourdon tube. All three components combine to form a closed tube system. The internal pressure in the system changes with the adj ... More
