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 are the factors influencing the response times of thermowells and protection tubes?

Put simply, one can say that the more stable a thermowell or protection tube 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 interio ... More

Do thermowells or protection tubes need to be CE marked?

Thermowells or protection tubes must not be CE marked, in principle. An exception as a result of its special design is the model TW61 thermowell with DN>25, suitable for orbital welding. This must be CE marked in accordance with the Pressure Equipment Directive ... More
