Optical Liquid Level Switch


SST Sensing Ltd - Liquid Level Sensors from SST Sensing Ltd on Vimeo.

In many applications, engineers need to detect the presence or absence of liquid. That’s where SST comes in, offering their single-point optical liquid level sensor range.

A vast range of sizes, materials, housing styles and electrical connections are available to meet your needs.

SST’s optical liquid level sensor range are unlike other technologies…they have a long operating life, low sensitivity to ambient light and are solid state – so there are no moving parts to fail. Their ability to function in wide operating temperatures and harsh liquid media result in a highly reliable sensor for use in extreme conditions!

How does this sensor work? …

When in air the infrared light inside the sensor tip is reflected back to the detector. When in liquid, the infrared red light is refracted out of the sensor tip causing less energy to reach the detector.

From low power switching and compact packages… …to those capable of handling higher voltage inputs and a larger output drive…

…Preventing expensive damage, flooding or run-dry operation in level control systems is a common application of our sensors.

An example of this is monitoring fluid tank levels in off road construction vehicles.

Sometimes you just need to know if liquid is somewhere it shouldn’t be in order to protect valuable equipment and service interruption.

A common example of this is in outdoor telecommunication enclosures.

If our standard optical liquid level sensor range do not meet your needs our engineers will work with you to find the right sensing solution.
