Optical Liquid Level Switches

Optical liquid level switches for industrial and OEM applications

SST optical liquid level switches are designed for applications where dependable liquid detection is essential. They can be used for high- and low-level alarms, pump protection, dry-run prevention, leak detection, fluid presence monitoring and automatic process control.

The product range includes:

• Liquid level switches for industrial tanks and reservoirs
• Optical sensors for coolant and water-glycol monitoring
• Level switches for leak detection trays and containment systems
• Compact sensors for OEM equipment and instrumentation
• Chemical-resistant sensors for demanding liquid media
• Hazardous-area-approved liquid level switches
• Glass-tip sensors for specialist applications
• Custom Sensor Solutions with application-specific housings, cables and connectors

These sensors exhibit low sensitivity to ambient light and are unaffected by foam in air or small bubbles in liquid. They are engineered to operate in wide temperature ranges and withstand harsh liquid media, ensuring robust, long-lasting functionality even in challenging conditions.

If our standard switches don’t meet your needs, we provide customization options for housings, cabling, and connectors to suit your specific applications. Additionally, bespoke features such as PWM outputs or insensitivity to moving liquids can be integrated, delivering a solution tailored to your unique requirements.
