Brief description
The contact thermometer is a universally applicable instrument with indication of the actual
value, for temperature measurement, control and monitoring.
The temperature-dependent change in volume of a liquid-filled measuring system (or the
temperature-dependent change of pressure in a gas-filled system) is converted into a rotary
movement of the pointer by a Bourdon tube, without any intermediate gearing. The rotary
movement of the pointer spindle operates the microswitch through a lever system.
