JS - HG series water transmitter is a photoelectric detector and transmitter integrated machine, using infrared electric principle, when the measured liquid contact the sensor surface, the light path changes, infrared receiving tube is in the cutoff state, triggering reverser flip, then output show low level absorption current state. It's fully sealed design ensure the high precision and reliability.This product has high sensitivity, fast response time, using and installation easily.
This series of products used for communication base station, precision machine room, library, hotel, restaurant,warehouse and some other place need to have water alarmed.
Transmitter and sensor integration design, light refraction principle, prevent DC polarization, strong anti-interference capability, high reliability
