OLS7 Series Optical liquid level sensor 1/4”NPT mount Low cost sensors for general liquid sensing High reliability optical sensing External mount via 1/4”NPT thread Standard temperature range -25ºC to +80ºC Extended temperature range -40ºC to +125ºC High and Low output versions Technical Specification The OLS7 series is a liquid level sensor for single point liquid level detection. The sensor has an infra-red emitter and detector aligned within an accurately shaped cone to give good optical coupling when the sensor is in air. This coupling is greatly reduced, when the sensor is immersed in liquid, as the infra-red light escapes through the liquid rather than being reflected back to the detector. The sensor has a transistor output, so can be configured by the user for particular applications.

OLS7 Series Optical liquid level sensor 1/4”NPT mount Installation The sensor can be mounted in either the side or the bottom of a tank. It must not be mounted in the top of a tank with the cone downwards. This sensor requires a 1/4”NPT thread socket connection. The sensor should be screwed into the 1/4”NPT socket but should not be overtightened. Cleaning Proper fluids should be selected based on the type of contamination to be removed. It is recommended that freon or alcohol based solvents are used. DO NOT USE chlorinated solvents such as trichloroethylene as these are likely to attack the sensor housing material. Liquid Media Compatibility Check that the fluid in which you wish to use the sensor is compatible with Polysulfone.
