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. 

FEATURES
*  Liquid level switches that can detect almost any liquid type; oil or water based
*  Large load output; high switching currents
*  Choice of threads and terminal connections

BENEFITS
*  Robust stainless steel housing
*  Suitable for use within aggressive environments
*  Larger mounting threads; standard or custom
