Brief description

Explosion protected surface-mounting thermostats of the ATH-Ex type series control and
monitor thermal processes and can be directly used in explosive areas - Zone 1 and Zone 21.

The devices are available as temperature monitors TW and fail-safe temperature monitors STW.
The thermostats operate according to the fluid or gas expansion principle. The electrical
switching element is a pressure-resistant encapsulated microswitch.

Design as per DIN EN 14597:

Data Sheet 605041 Page 2/6

Temperature monitor TW
and fail-safe proof temperature monitor STW

If the temperature exceeds the setpoint value set on the temperature
probe, the microswitch will be tripped by the transmission mechanics
and the current circuit opened or closed.

The microswitch is reset to its original status once the setpoint value
set is gone below (by the hysteresis).

Self-monitoring
for the fail-safe temperature monitor STW

If the measuring system is destroyed, i.e. if the expansion fluid
emerges, the pressure in the STW diaphragm drops and permanently
opens the current circuit. Unlocking is no longer possible.

If the probe has cooled down to a temperature within the control
range table, e.g. below -20°C, the current circuit is also opened. The
STW is automatically restarted.
