Photoelectric Liquid Level Sensor

Photoelectric Level Sensor Series

This series is designed for tube installation, detecting the presence or absence of liquid inside a tube using an optical principle, ideal for low-flow fluid monitoring.

Core Principle: Utilizes the difference in refractive index between liquid and air. When the tube is empty, light undergoes total internal reflection to the receiver; when liquid is present, light refracts away, triggering the switch.

Key Characteristics:

Specialized Design: For use with transparent or semi-transparent tubes with diameters of Φ6-13mm.

Convenient Functions: Features output action switching (NO/NC) and sensitivity adjustment, supporting one-button setting.

Eco-Design: Uses environmentally friendly wiring without powder release agents.
