Product Overview
The BE-A Series Optical Bubble Sensor is a compact, precise, and easy-to-use device designed to reliably detect liquid and air bubbles in small diameter tubes. Featuring hassle-free one-touch attachment without tools, it seamlessly integrates with applicable tube sizes (2 mm, 3 mm, 4 mm) without obstructing flow rate. With a high-speed response time and built-in amplifier, it offers immediate usability and is compliant with a wide range of power supply voltages (5 to 24 V DC). Equipped with two outputs (Liquid-absent-ON/Liquid-present-ON), it is ideal for applications requiring traceability in analysis processes, precise liquid dispensing, and empty detection.
