Micro flow switch and bubble detector for liquids
Its output signal of either 0 or 5 volts indicates whether the current flow rate is above or below the specified flow switch level. At continuous flow rates above this limit the identification of air bubbles within the flow channel is equally consistent. Maximum flow rates are accepted up to 220 ml/min. Fluidic connections can be made via ¼-28 standard fittings, suitable for connecting plastic tubing with outer diameters of 3.2mm or 1.6mm. Barb connector adapters are available as an alternative. The tiny, light sensor is designed for integration into bio-medical applications and general process control solutions. An excellent chemical resistance and bio-compatibility are ensured by its non-invasive measurement through the wall of the straight, internal glass capillary (diameter 1.8 mm) and fluidic connectors made of PEEK high-end plastics.
