Mechanical temperature sensors
Our range of mechanical temperature gauges
There are two different options when it comes to mechanical temperature gauges, namely a bimetal or gas pressure thermometer. Both take advantage of the fact that materials or gases expand or contract with a change in temperature.
A bimetal thermometer is two connected strips of metal with different coefficients of expansion. From this results a curvature and that is the measure of temperature. A gas pressure thermometer is filled with a gas or gas mixture. As the gas expands, a pointer is set in motion. It is even possible to generate an electrical output from a mechanical sensor as well.
