BL Series

Liquid Level Photoelectric Sensors

The BL series photoelectric liquid level sensors can detect the presence or absence of liquid in transparent pipes measuring 6 to 13 mm in diameter and less than 1 mm thick. Users can easily select between Light ON and Dark ON operation using the operation mode switch. With a compact design and easy installation, the BL series sensors are ideal solutions for non-contact detection of liquid in transparent pipes.
