OLS7 Series Optical liquid level sensor 1/4NPT mount Low cost sensors for general liquid sensing High reliability optical sensing External mount via 1/4NPT thread Standard temperature range -25C to +80C Extended temperature range -40C to +125C High and Low output versions Resistant to false triggering caused by foaming Technical Specification Mounting style External Cable length - standard 25cm Mounting thread 1/4NPT Wire size 24AWG Body material Polysulfone UDEL 1700 Cable conductor material Tinned copper Temperature Range -25 to +80C/-40 to +125C Wire sheath material PTFE Maximum pressure7bar Wire temperature rating 125 C The OLS7 series is a liquid level sensor for Tightening torque for fixing1.5Nm/13.26lbs in Sealing gasket Not supplied single point liquid level detection. Electrical Specification Supply Voltage (Vs) Vdc 4.5 to 15.4 or 10 to 28 The sensor has an infra-red emitter and Supply Current Max (Is) mA 2.5 (Vs = 15.4Vdc) detector aligned within an accurately Output type Voltage High or Low shaped cone to give good optical coupling Output Voltage (Vout) Iout=100mA Output High Vout = Vs-1V max Output Low Vout = 0.5Vmax when the sensor is in air. This coupling is Output Sink & Source Current Iout 100mA max or 1A 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. Sensor connections Red= supply +ve, Blue= common(0V), Green= Output (see diagrams overleaf) The sensor has a transistor output, so can Standard Parts Mount Temp Range C Supply Volts V Output be configured by the user for particular OLS700D3SH 1/4NPT -25 to +80 5 to 15dc High in air Volts applications.

It must not be mounted in the top of a tank with the cone downwards. Installation in 1/4NPT socket This sensor requires a 1/4NPT thread connection. 1/4NPT socket The sensor should be screwed into a 1/4NPT socket and should not be Red wire =+Vs overtightened. Green wire =Output Blue wire = 0V 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.
