GENERAL DESCRIPTION：
The LLC Basic Series liquid level sensor provides a single point detection for high volume OEM applications. The sensor contains an infra-red emitter and detector accurately positioned to 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 detector. This configuration allows the customer to tailor the sensor electronics (supply voltage, protection etc) to their unique application.
