Bimetallic dial thermometer

Bimetal thermometers

Function of a bimetal thermometer

The measuring element consists of two,welded together, metal tapes. The tapes having different coefficients of thermal expansion. The coiled measuring element is fixed at the end of the stem; the other side being connected to the pointer axle.

Specialized Properties

The bimetal stretches or bends itself in case of a change in temperature, causing the coiled element into a turning movement. This movement is proportional to the change in temperature and is indicated on a dial.

Application purposes

Bimetal thermometers are used for temperatures from – 50°C up to +500 C. Accuracy is ± 1,6% of full scale deflection.
