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 minimum insertion length of a thermowell?

The insertion length of a thermowell will be specified through the thermometer  used. In general one can assume a length of  60-100 mm for mechanical thermometers from a minimum total length. Electrical thermometers need an insertion length of at least 35 ... More

What are the factors influencing the response times of thermowells?

Put simply, one can say that the more stable a thermowell is constructed, the slower it reacts to temperature changes. In order to optimise the response time, there are thin wall thicknesses and low air space between sensor and the bore's interior walls. Further op ... More
