Dial thermometers

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.

Why is liquid damping in bimetal thermometers only possible up to medium temperatures of 250°C?

Since the filling liquid (silicone oil) in the complete thermometer (i.e. it is also present in the stem) this means the filling liquid is heated to the temperature of the medium.  This can lead to fire in the silicone oil.

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
