The optical liquid level switch consists of an infrared LED and a receiver. In air, the light beam from the infrared LED is reflected back into the receiver. When rising liquid touches the tip of the sensor, the light is refracted away from the device, causing little light to return to the receiver. Sensing this change, the sensor outputs a signal to activate or stop other devices. Engineers usually use the sensor to detect the presence of liquid or monitor the leakage. This series is easy to install and do not need adjustment or alignment. Polysulfone housing improves high chemical resistance to most acids and bases.
