China [CN] Optical Liquid Level Sensor with an Infra-Red LED
Model Numder:LLC210A3SH
DESCRIPTION
The liquid level sensor provides single point liquid detection via a TTL compatible push pull output.An infra-red LED and phototransistor accurately positioned at the base of the sensing tip ensure good optical coupling between the two when the sensor is in air. When the sensing tip is immersed in liquid, the infra-red light escapes from the cone causing a change in the amount of light present at the phototransistor which makes the output change state.
CLEANING
Proper fluids should be selected based on type of contamination to be removed. SST Sensing recommends freon and alcohol based solvents. DO NOT use chlorinated solvents such as tricholorethane as these are likely to attack the sensor material.
Liquid Media Compatibility
Before use check that the fluid in which you wish to use these devices is compatible with polysulphone.
