Point-Air Detection (PAD) Sensor PAD Sensor Introtek’s Point-Air Detection (PAD) Sensors 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. Applications Air bubble, air-in-line and liquid level sensing Medical Devices (patient-connected) such as: Apheresis, Auto-transfusion, Infusion Pumps, Heart Lung Bypass, Dialysis, Cardiac Assist Pumps, Perfusion-based "Life Support" Devices Chromatography and separations technology Immunoassay and diagnostic equipment Liquid and chemical dispensing Blood processing equipment

View Printer Friendly Version   Measurement 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 Options Reverse output logic Custom OEM designs Custom response times Dual redundant operations
