PZ probe for PZ-828 SONDA-PZ

Single-stage relays are used to detect the presence of electrically conductive liquids at the level of the mounted flooding probe. When dry, the relay contact remains in position 7-4. When the probe is flooded with liquid (i.e. the probe electrodes are short-circuited), the relay contact is switched to position 7-8. After the liquid level drops (the probe electrodes are opened), the relay contact returns to position 7-4. The design of the probe allows it to be mounted on a flat horizontal surface, e.g. on the floor in a room with hydro valves, flow pipes or in a laundry room, which allows for quick detection of failures and flooding of the room with liquid while switching off the electrical circuits or activating the sound or light signaling (alarm) . The probe cable can be extended up to 100m
