LLHPA650L1 High Performance Metal Housed Liquid Level Sensors
Liquid Level Switches
High Performance Series
GENERAL DESCRIPTION
The High Performance liquid level sensor provides a single point detection via various electrical outputs to suit different applications.
sensor range designed for aggressive environments, capable of withstanding high and low temperatures and mechanical shock and with options for high switching currents.
An infra-red LED and phototransistor accurately positioned at the base of the tip ensure good optical coupling between the two when the sensor is in air. When the sensor’s tip is immersed in liquid, the infra-red light escapes from the tip causing a change in the amount of light at the phototransistor which makes the output change state.
