Optical Liquid Level Sensors LLC Industrial Series

General Description
The LLG Industrial Series liquid level sensor provides a single point detection via a TTL compatible output. Sensor range was designed to directly switch incandescent indicators, sounders or relays. An infra-red LED and phototransistor accurately positioned at the base of the cone ensure good optical coupling between the two when the sensor is in air. When the sensor’s cone is immersed in liquid, the infra-red light escapes from the cone causing a change in the amount of light at the phototransistor which makes the output change state. Various electrical outputs are available to suit different applications.
