WDS300 signals when water appears between its terminals. It is necessary the liquid to has conductivity close or better tap water's. Sensor will not work with distilled water. After the liquid withdraw the sensor will restore its initial state.
The sensor is intended for emergency signaling and not as an operational level sensor in automation systems. It is supposed to be dry 99% of the time and only in case of an accident is there contact with water. The contact surfaces are not corrosion resistant!
The WDS300 sensor is designed to be mounted vertically: the metal electrodes point to the surface to be monitored for water. Since the electrodes are 2mm inwards from the edge of the case, it can be mounted as close as possible to the floor surface, making sure that the liquid can pass trough to the electrodes ( if the surface is elastic). The double-sided adhesive on the back can be used for attaching the sensor to suitable vertical surface.
Connection to NetControl
The WDS300 connects to Sensor 1..4 external sensor inputs (depending on the model). In the NetControl WEB interface, the corresponding input must be set to "Contact Switch (Alarm)" mode. The presence of water between the electrodes will be written as "CLOSED" in the NetControl interface; "OPENED" will be in the absence of water. If SNMP is used for tracking the sensor: in the absence of water, the ADC will return a value of about 930 units; in the presence of water: the value will approach to 0 units (be sure to do an individual test of the values in both cases with the expected water source, as conductivity also varies greatly!).
