Optical Liquid Level Switch (Polysulfone)
Optical level switches are used for the detection of liquid level. With no moving parts, they are used to meet the needs of food processing facilities, for example. It is easy to use these sensors to control the fill point for water, oil or other water-based liquid. The installation is simple and consumes little space. Also, we provide two operating temperature range in standard: -20~65°C and extended operating temperature: -20 to 100°C for the polysulfone housing.
