The sensor must be used together with a "WLC / Water leak cable". The sensor reacts to just a few drops of liquid and can also detect the emergence of moisture. The cable is flexible and easy to install. Max. distance from the unit is 100 meters. VT591 is an analog plug-and-play sensor, it is integration-friendly and quick to reset. After the flooding, the leak detection cable can be dried and reused. The sensor does not produce false alarm signals when bent or twisted. Detectable liquids: clean, polluted & distilled water; acids; alkalis; alcohols, and other electrically conductive liquid. WLC can work in high humidity, pollution, and hazardous waste.
