Dial thermometers are universal temperature indicators for monitoring the temperature. The
instruments feature a plastic housing with a liquid-filled measuring system.
The temperature-dependent change in volume of the liquid-filled measuring system is
converted into a rotary movement of the pointer by a Bourdon tube, without any intermediate
gearing.
