Product Overview
The Panasonic 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 a hassle-free one-touch attachment without tools, it ensures a perfect fit for applicable tube sizes (2 mm, 3 mm, 4 mm) without obstructing flow rate. With a high-speed detection capability and built-in amplifier, it offers seamless integration and immediate operation. The sensor is compliant with a wide range of power supply voltages (5 to 24 V DC) and equipped with two outputs (Liquid-absent-ON / Liquid-present-ON) for versatile application.
