5 advantages of optical level sensors over conventional float switches

5 advantages of optical level sensors over conventional float switches

Hi, I’m Michael from SST Sensing and I want to talk about our optical liquid level switches, and the benefits of our sensors over conventional float switches.

Our sensors are used all over the world and a wide range of applications.

From run-dry pump protection, leak detection and high and low alarm systems.
They are used to protect vital machinery, to detect level of fluids in vehicles and also to tell when there is liquid where it shouldn’t be.
Our sensors have many benefits over conventional float switches and I’m going to discuss five of those today.

One, our sensors are small, so only the sensor tip has to be in the process, making it ideal for applications where space is at a premium or maybe there is obstacles in the tank, such as agitators.

Two, they are solid-state, this means there is no moving parts to get clogged, broken or corroded.

Three, they are sensitive. Our sensors need a tiny amount of liquid for the sensor to change state, again this sometimes can’t be the case with a float switch, where you need quite a lot of displacement for the float to move enough to change.

Four, scope of applications. Our sensors come in a wide range of chemically compatible plastics and glass. It can be used to detect almost any liquid, including most oils and emulsions. They can also be used in a wide range of temperatures and pressures.

Five, customisation. Here at SST we pride ourselves on being able to supply the correct sensor for your application. If our standard range of sensors don’t suit, then our engineers have the experience and knowledge to design a bespoke sensor for your application. Be this changing electrical termination, process connection or even the output state of the sensor itself, these are well within our capability and something we are more than happy to do.

So to summarise, our sensors are small, solid-state and sensitive, suitable for a wide range of applications and can be customised to suit your needs.

So if you are a design engineer or manufacturer and you are looking for a small, robust level sensor from a company who is flexible enough to meet your application needs, then get in touch with us at SST Sensing where we will be more than happy to help.
