Mechanical Trafag thermostats are used in applications where temperatures are controlled by means of a simple electrical on/off switching signal. These instruments operate failsafe under harsh operating conditions (e.g. extreme fluctuation of ambient temperature) and are insensitive to outside environmental conditions.
The medium in a capillary tube reacts to temperature changes on the principle of heat expansion. This expansion is measured by means of a fine mechanical construction which activates one or several micro-switches.
