FS20701 Rail - Mounted Water Immersion Sensor For Extensively Applied In Places That Require Water Leakage Alarm Functions
General Description:
The FS20701 is a rail - mounted water immersion sensor equipped with external sensing electrodes. It operates based on the principle of liquid conductivity. In normal conditions, the two - pole probe maintains insulation through air. Once the probe is immersed in water, it turns conductive, prompting the sensor to output a dry contact signal. When the water immersion height exceeds the preset threshold, the sensor triggers an alarm signal immediately. After being powered on, the sensor conducts a self - test and can output monitoring results in approximately 3 seconds. It adopts the standard Modbus - RTU communication protocol and RS485 signal output, enabling users to configure the device address, communication baud rate, and detection sensitivity to adapt to diverse environmental detection needs.
Core Features:
- The sensor electrodes come with anti - oxidization performance, which significantly extends the product's service life in various working environments.
- It boasts a reasonable structural design, along with high reliability and sensitive response. There are no adjustable components, simplifying operation while ensuring accurate alarm reporting without false alarms.
- It exhibits strong signal compatibility and can be easily integrated into centralized monitoring systems, meeting the connection and monitoring requirements of different supporting devices.
- With a wide operating voltage range of DC 10 V - 30 V, it can adapt to various power supply scenarios in industrial and commercial settings.
Typical Applications:
This sensor is extensively applied in places that require water leakage alarm functions, including communication base stations, computer rooms, libraries, archives, warehouses, equipment cabinets, hotels, hospitals, subway stations, industrial workshops, and production parks.
