Frequently Asked Questions
How does an optical liquid level switch work?
An optical liquid level switch uses an infrared LED and photodetector contained within the sensor tip. When the tip is surrounded by air, light is reflected internally. When liquid contacts the sensing tip, the light path changes, allowing the sensor to detect the presence or absence of liquid and generate an output signal.
What are the benefits of using an optical liquid level switch?
Optical liquid level switches offer fast response times, no moving parts, high reliability, and low maintenance requirements. Their compact design makes them ideal for OEM equipment and industrial applications where accurate point-level detection and long service life are important.
