Non-Invasive Ultrasonic Air Bubble Sensor AD8/AD9 non-invasive air bubble & air-in-line sensors incorporate the latest ultrasonic technology. Introtek AD8 (for rigid tubing) and AD9 (for soft tubing) sensors incorporate the latest generation of 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 programmable to specific requirements. Our patented pulse-type ultrasound provides highly reliable, noninvasive air detection capabilities in critical applications where the safety of a patient or the integrity of a process is essential.
