Technical data
Switching function
Temperature monitor TW
and fail-safe proof temperature monitor STW
Self-monitoring
for the fail-safe 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).
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.
