The Leakage sensor Leak includes an evaluation unit and a probe. If there is water between the electrodes of the probe, the evaluation unit produces an acoustic alarm.
Additionally, the alarm output of the evaluation unit switches on. The output can be used to transmit the alarm signal to other systems (e.g. klaxons, light indicators, stop valves, building control system, alarm system). The changeover contact design of the output makes it possible to detect wire breakage in the alarm line by suitable systems.
