echnical Specification
The OLS2 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.
Output is via TTL compatible push pull
output.

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 hole of 12mm minimum or an M12x1 thread socket connection. The hole should be in a flat
surface and be free of burrs.
The sensor with suitable gasket should be inserted into the hole and a fixing nut fitted on the M12 thread on the inside
of the tank. Alternatively the sensor can be screwed into a M12x1 socket. The sensor 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.
