    Overview

    DIN rail water leakage sensor with controller for sale online. The SUCH water leakage sensor comes with a rail-mounted controller, featuring sound + indicator light on-site alarm, RS485 communication, and a response time of <3 seconds. This highly sensitive water leak sensor is suitable for various locations with a risk of water leakage or immersion, such as communication base stations, precision machine rooms, libraries, warehouses, basements, or monitoring rooms.

    Feature

    • Waterproof and Dustproof: The water leakage sensor is sealed with epoxy resin and can be completely immersed in water.
    • Corrosion-resistant and Wear-resistant: The alloy shell and 316 stainless steel probe electrodes effectively prevent rust and corrosion from damaging the water leak sensor.
    • Widely Applicable: Suitable for various locations with a risk of water leakage or immersion, such as computer rooms, warehouses, and factories.

    FAQ
    ❯

    Water leakage sensors are typically installed by placing the sensor probe or detection cable in areas prone to water leaks. For standalone sensors, simply place the sensor on the floor or near the equipment, then connect the power supply or install the batteries. For wired or DIN rail systems, the sensor needs to be connected to a controller, the controller mounted on a DIN rail, and the necessary power supplied.

    ❯

    Water leakage sensors should be placed at the lowest point where water is most likely to accumulate, such as under pipes, near water heaters, air conditioning units, water pumps, sinks, server racks, or near floor drains. The detection cable can be routed along pipes or around equipment to cover a larger area.

    ❯

    To reset the sensor, remove the water source, dry the sensor probe or detection cable, and then wait for the sensor to return to its normal state.

    reliable water leakage sensor with controller
    I’ve got this water leakage sensor with controller near some equipment that can’t really afford a leak. Tested the alarm with a bit of water before leaving it there, and it picked it up right away. Nothing to complain about so far. It’s been sitting there quietly, which is exactly what I wanted.
