The principle and characteristics of water sensor1

Water sensor is based on liquid conductive principle, using electrodes to detect whether there is water, then use the sensor into a dry contact output. Here is a project for you on the water sensor nine characteristics:

1, reasonable structure, high reliability, no parts, easy to operate, never ignore any alarm, also won't false alarm.

2, non exposed metal structure, special polymer structure makes cable corrosion resistance, high strength, reliable quality.

3, simple monitoring panel, clear indication system status, self correction, modular design, expand the configuration ability strong, easy installation, maintenance, replacement.

4, rapid detection and real-time response, reduce leakage to the smallest degree of danger.

5, high positioning accuracy and the error is not more than one over one thousand.

6, monitoring range, a single controller detection distance up to 1500 meters.

7, after the water leak sensor, controller of relay output can be control valve is closed, to cut off the source of liquid, to avoid the accident.

8, good adaptability, strong compatibility, with multiple signal interface, not only have a relay output, and RS - 232485 communication interface, convenient and included in the centralized monitoring system.

9, advanced water sensor product, its role is detection cable on every part to see if there is abnormal, different from the old induction leak point products; Can accurate positioning and can detect the rope fracture, is different from ordinary sensing cables.
