The BE-A401 is an optical bubble sensor designed for non-invasive detection of air bubbles in transparent resin tubes. It features a one-touch attachment mechanism that does not require tools or tube cutting. The sensor is capable of detecting air gaps as small as 0.8mm with a high-speed response time of 20 microseconds or less. It includes a built-in amplifier and two NPN open-collector outputs that can be switched between Liquid-absent-ON or Liquid-present-ON operation.
