In this video, learn how SST Sensing’s optical liquid level sensors provide fast, dependable liquid leak detection using proven infrared optical sensing technology. Designed with no moving parts, these solid-state sensors accurately detect the presence of liquid, helping engineers identify leaks before they become major operational problems.
Unlike traditional mechanical float switches, optical liquid level switches are resistant to sticking and mechanical wear, making them an ideal choice for continuous monitoring in demanding industrial and OEM environments. Their compact design, fast switching response, and wide range of material options allow them to be integrated into systems handling water, oils, coolants, chemicals, and many other liquids.
Typical applications include:
- Data centre liquid cooling systems
- Hydraulic reservoirs
- Petrochemical and chemical processing
- Hydrogen generation equipment
- Industrial compressors
- Tank and container monitoring
- Water treatment systems
- OEM machinery and process automation
Whether protecting expensive equipment, preventing environmental contamination, or improving system uptime, SST Sensing’s optical liquid level switches deliver reliable, maintenance-friendly leak detection across a broad range of industries.
Frequently Asked Questions
How does an optical liquid level switch detect a leak?
An optical liquid level switch uses an infrared LED and phototransistor within the sensing tip. When liquid contacts the tip, the infrared light path changes, allowing the sensor to instantly detect the presence of liquid and activate an alarm, control system, or shutdown sequence.
Why use an optical liquid level switch instead of a float switch for leak detection?
Optical liquid level switches have no moving parts, making them less susceptible to sticking, wear, or mechanical failure. They provide fast, repeatable liquid detection, require minimal maintenance, and are ideal for applications where reliable leak detection is critical.
