Highly reliable air bubble and air-in-line sensors for critical applications

Sensortechnics introduces the AD8/AD9 series of non-invasive ultrasonic fluid monitoring sensors. These highly reliable sensors detect air or gas bubbles as well as ‘end of sample’ flowing through small tubing. The detectors are based on a special pulsed ultrasonic technology which permits highly accurate and repeatable detection. The non-invasive design eliminates all media compatibility and sterility issues. Detection can be carried out in a large variety of soft or rigid tubing with diameters from 1.6 to 25.4 mm. The sensors are very compact and feature an integral programmable micro-controller to allow for custom sensor functionality or specific algorithms. Typical applications include chromatographs, analytical instruments and dispensing or liquid filling machines.
