Optomax LLC - - Liquid Level Sensors Datasheet

© 2011 SST Sensing Ltd 1 www.sstsensing.com DS0032 rev10 Please follow all safety information GENERAL 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 either with polysulphone or trogamid. Installation Instructions for Standard and Extended Temperature Optomax Series Liquid Level Sensors Supply Voltage (Vs) +4.5 Vdc to +15.4Vdc Supply Current (Is) Max 2.5mA (Vs = 15.4Vdc) Output Type An “L” in the part number after D3 indicates that the sensor output will be low in air. Otherwise the output will be high in air.
