High-quality photoelectric leakage detection sensors can detect liquids such as alcohol, tap water, purified water, acidic/alkaline water, gasoline, and antifreeze. SUCH water leakage sensors operate on a DC 10-30V power supply and offer optional RS485 or relay output. They are dustproof and waterproof, and widely used in communication base stations, computer rooms, libraries, archives, warehouses, equipment cabinets, and other locations requiring water alarms.
A photoelectric leakage sensor is a sensor that uses photoelectric detection to determine whether a water or liquid leak has occurred. It is mainly used to detect the presence of liquids. It typically identifies the presence of liquid in the detection area by detecting changes in the optical path between a light source and a photoelectric receiving element, thereby triggering a leak alarm or control output.
The photoelectric water leak sensor contains a transmitter and a receiver. When the detection area is dry, light travels along a set path and is received normally by the receiver. Once water or liquid enters the detection area, refraction, reflection, or obstruction occurs, causing a significant change in the received light intensity. The sensor circuit then determines this as a leak and outputs an alarm or switch signal. Because it is based on optical changes, this type of sensor has a fast response speed and does not depend on the conductivity of the liquid.
