Optomax Industrial Glass Series Liquid Level Switches Description
The Optomax Industrial Glass range liquid level switches can operate in aggressive environments due to their stainless steel and glass construction while offering industrial supply voltages and outputs that can directly drive loads.
The microcontroller based Optomax Industrial Glass Range liquid level switches are solid state, incorporating an infra-red LED and phototransistor which are optically coupled by the tip when the sensor is in air. When the sensing tip is immersed in liquid, the infra-red light escapes making the output change state. The sensor can detect the presence or absence of almost any liquid type; oil or water based. It is insensitive to ambient light and is not affected by foam when in air or by small bubbles when in liquid.
A range of N and P type output configurations can sink or source up to 1A at supply voltage ranges from 4.5 to 15.4Vdc or 8 to 30Vdc and can be configured to output a high or low signal in either a wet or dry state. Options for connecting to inductive loads or digital interfaces are also available.
With housing threads suitable for external sensor mounting and for use in two operating temperature ranges; Standard (-25 to 80'C) or Extended (-40 to 125'C).

1.General description
The liquid level sensor provides a single point detection via a
Ttl compatible output.
An infra-red led and phototransistor accurately positioned at
The base of the cone ensure good optical coupling between
The two when the sensor is in air. When the sensor’s cone is
Immersed in liquid, the infra-red light escapes from the cone
Causing a change in the amount of light at the phototransistor
Which makes the output change state.
2. 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.
3.Liquid media compatibility
Before use check that the fluid in which you wish to use these
Devices is compatible with polysulphone.

OEM Optical Water Sensor Water Level Sensor
Whilst maintaining our very competitive pricing, the Optomax Industrial range of liquid level sensors offer higher supply voltage ranges, higher current drive options and an extended temperature range for more challenging specifications and environments.
SST has improved this range of industrial level sensors and introduced new features such as;
Low power consumption, reducing supply current from 15mA to 2mA
Increased output power, increasing output sink and source current from 500mA to 1A
They are solid state, no moving parts unlike mechanical switches where debris can get jammed and cause unreliability.
Very accurate and precise readings
Easy to install, saving assembly time
Very robust which permit use in a wide range of fluids and chemicals
Housings, cabling and connectors are made to your requirements
High pressure options available
