ATH series

Surface-mounted double thermostats of the ATH series consist of 2 separate measuring and switching systems. The devices are available as temperature controllers (TR), temperature limiters (TB), temperature monitors (TW), safety temperature monitors (STW), and safety temperature limiters (STB).

Thermostats are used to control and monitor thermal processes. Surface-mounting double thermostats of the ATH type series consist of two separate measuring and switching systems. The devices are available as temperature controllers TR, temperature monitors TW, safety temperature monitors STW (STB) and safety temperature limiters STB. In the event of a malfunction, the STB switches the monitored machine line to an operationally safe status. Surface-mounting double thermostats operate according to the fluid expansion principle, a microswitch serves as an electrical switching element.
