Description
The water leakage sensor/transmitter is widely used in communication base stations, hotels, restaurants, server rooms, libraries, archives, warehouses, equipment cabinets, and other areas requiring water accumulation alarms. It features a unique AC detection technology that effectively prevents the sensitivity of the immersion electrodes from decreasing due to oxidation over prolonged use.
The RS485 sensor outputs in standard ModBus-RTU, with a maximum communication distance of 2000 meters, allowing for direct integration with on-site PLCs, industrial instruments, configuration screens, or configuration software. External leak electrodes can reach a maximum distance of 2600 meters, and it also supports leak ropes up to 2600 meters long. The device is housed in a high-protection waterproof shell, making it suitable for long-term use in humid and high-dust environments.

Applications
Tips: Working principle of water leak sensor/transmitter
- Detection Electrodes: The sensor is equipped with multiple electrodes. When water comes into contact with these electrodes, it completes an electrical circuit.
- Current Variation: The conductivity of water causes a change in the current. The internal circuitry of the sensor monitors this variation to determine if a leak is present.
- Signal Processing: Once moisture is detected, the sensor sends the signal to a built-in processing unit for analysis and verification.
- Alarm and Output: If a water leak is confirmed, the sensor issues an alarm via RS485 or relay output, transmitting data to a monitoring system or PLC to ensure timely user intervention.
- Remote Monitoring: Utilizing the ModBus-RTU protocol, the sensor can communicate with other devices for remote monitoring, allowing users to manage and track conditions in real time.
