Thermostat Trafag

In the thermostat, a liquid enclosed in a sensor expands on exposure to heat and induces a bellows system. This in turn actuates a micro switch via a high-precision mechanism. The switch closes or opens a signal loop. Thermostats do not require any electrical energy supply. Thermostats from Trafag enjoy an outstanding reputation. Being fully maintenance-free, they can be in nonstop use for several decades without any loss of accuracy.
