The water leakage alarm utilizes alternating current to collect inductance parameters of accumulated water, accurately distinguishing whether water immersion has occurred. The electrodes, even when immersed for extended periods, do not undergo electrophoresis polarization. It does not rely on special electrodes, ensuring long lifespan and reliable detection. This effectively avoids the issue of decreased leakage sensitivity caused by oxidation of immersed electrodes due to prolonged operation;

The equipment adopts a waterproof shell with high protection level, which can be used in harsh environments such as damp and high dust conditions for extended periods of time;

The device can be externally connected to a water leakage electrode up to a maximum distance of 2600 meters, and can also be connected to a water leakage rope up to 2600 meters in length. Any part of the rope that detects water can generate a water leakage alarm message;

Using 485 network communication, it can significantly reduce the risk of false alarms and missed alarms compared to commonly used on-off type water immersion transmitters on the market. In the working state, the contacts of an on-off type water leakage alarm only output two states: open or closed. And when the device fails and cannot function normally, the contacts still only output open or closed states. This makes it impossible to distinguish whether the on-off type water immersion transmitter is in a fault state or a normal working mode in the monitoring system. In comparison, the advantage of using 485 network communication for water leakage alarms is very obvious. The system can accurately determine whether the device is in an alarm state, a normal state, or a fault state, and ultimately reflect these three states in the monitoring system software.
