Explosion proof temperature controller and limiter
STAHL
In case that the setpoint is overflow the controller switches off. After the temperature drops below the setpoint the temperature controller can be reset manually.
When the system leaks the temperature controller remains in the off-position. When the sensor temperature drops below the minimum the circuit opens but closes again when the temperature rises.
