The BE-A301P is an ultra-compact optical bubble sensor designed for detecting air gaps and bubbles as small as 0.8mm in 3mm outer diameter PFA or transparent tubing. It features a high-speed response time of 20 microseconds and a non-modulated infrared LED sensing source. The device includes a built-in amplifier, requiring no sensitivity adjustment, and provides two PNP outputs for liquid-absent-ON and liquid-present-ON conditions. Its one-touch attachment design allows for tool-free installation without obstructing the flow rate of the liquid.
