Even a small liquid leak can result in costly equipment damage, production downtime, and safety risks if it isn’t detected quickly.
In this video, discover how SST Sensing’s optical liquid level sensors provide a dependable solution for liquid leak detection in industrial and OEM systems. Using proven solid-state optical sensing technology, our sensors detect the presence of liquid with no moving parts, delivering fast, reliable performance while eliminating many of the issues associated with mechanical float switches.
Optical liquid level switches are ideal for applications where early leak detection helps protect valuable equipment and maintain continuous operation, including:
- Data centre liquid cooling systems
- Refrigeration and cooling equipment
- Laboratory and analytical instruments
- Industrial machinery
- Fluid reservoirs and collection trays
- Marine and transportation systems
- Environmental monitoring equipment
Designed for long service life and minimal maintenance, SST Sensing’s optical liquid level switches help engineers improve system reliability, prevent fluid loss, and detect leaks before they become costly failures.
Frequently Asked Questions
How do optical liquid level switches detect liquid leaks?
Optical liquid level switches use an infrared LED and phototransistor housed within the sensor tip. When liquid contacts the sensing tip, the optical characteristics change, allowing the sensor to rapidly detect liquid and trigger an alarm or control signal.
What industries use optical liquid level switches for leak detection?
Optical liquid level switches are widely used in data centre cooling, battery energy storage systems, refrigeration, laboratory equipment, hydraulic systems, marine applications, industrial machinery, and OEM equipment where reliable leak detection and fluid monitoring are essential.
