The LLC Industrial Series liquid level sensor provides single point liquid detection via a TTL compatible output.
This  sensor  range  was  designed  to  directly  switch incandescent indicators, sounders, relays or applications which require higher output power.     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 detected at the phototransistor which makes the output change state. Various electrical outputs are available to suit different applications.       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 either polysulphone or trogamid
