The Wired Water Leak Sensor is Electrode-detection, according to electrodes changes in water resistance principle, conducted by the Application Specific Integrated Chip signal amplification, plastic, compared to the output of high or low alarm signal for the relay module. The PCB was designed of a photoelectric isolation, coil isolation, and isolation relays, and other safety measures.
Application:
Communications base station, precision machine room, hotels, restaurants, libraries, warehouses, urban water supply, buildings, water and other needs of the protection from water cases.
Functions & Features:
Electrode-detection: Low cost, high reliability;
Can work with any wired input alarm panel;
Easily to installation.
Specifications:
Size: 84mmX91mmX34mm;
Rated Voltage: DC12V;
Rate of false triggered: <100 ppm
The largest current (when the alarm): ≤ 40 mA
Output form: Dry relay (normally close nodes) high-low output (VL = 0 V, VH = 5 V)
Working environment: Temperature: -25degree-+50degree Humidity: Less than 20~100%
