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. Operating Principle 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. Features Compact design features integral MEC circuitry Programmable micro-controller expands the circuits functionality High EMI and RFI noise immunity Reliable pulse-type, non-invasive ultrasound Air detection threshold or bubble size can be set to our customer’s requirements Accommodates a wide range of disposable cassette assemblies that incorporate fluidic channels Dry coupled; no coupling gel is required Accuracy is not affected by fluid or tubing color Options Reverse output logic Custom OEM designs Custom response times Dual redundant operations Applications Air bubble, Air-in-line and liquid level sensing Patient-connected medical devices, including: • Apheresis • Heart-lung bypass • Auto-transfusion • Dialysis • Infusion pumps
