Specification
Thermostat TH20 is basically a singlepole automatic switch, based on principle of different temperature expansion of two metals. It is designed for thermoregulation in gas environment, heated by alternate current (electric ovens etc.), within its range. The core of these thermostats is a reliable mechanical system, that has no power consumption itself. They are known for significantly lower operational and maintenance costs compared to electric systems.
The thermostat consists of a stem and a switch head. The stem comprises of expansive tube and invar bar. For fitting purposes the thermostat is equipped with two holy risers. It is necessary to install the thermostat in a way, so that the lower part of the switching head is approximately 2 cm away from the body wall and this area is filled with insulating material, so that the head temperature does not exceed +120°C .
