PAD - Point Air Detector

PAD – Point Air Detector

INTROTEK® Non- Invasive, PAD Point-Air Detection, delivers a reflective ultrasonic signal from a single contact point. The ultimate air detection sensor for a fluid-handling cassette application. The PAD Sensor incorporate the state-of-the-art, patented pulse-type ultrasonic circuitry. Integral to the sensor’s assembly, the Micro-Electronic Controller (MEC) features programmable algorithms for functionality control. Response times, time delays, and other functions are programmed in accordance to specific requirements.

Introtek’s patented pulse-type ultrasonic technology provides highly reliable, non-invasive air bubble detection capabilities in the most critical applications where the safety of a patient or process is mandatory. Many of the variables, which can affect performance of amplitude or continuous wave based sensing systems, are eliminated or greatly reduced, thus yielding accurate and repeatable detection.
