The Introtek Advantage provides products of unsurpassed quality, functionality and dependability that are manufactured to the highest medical device standards and backed by a three-year warranty. AD8/AD9 Series Sensor The AD8/AD9 ultrasonic air bubble, air-in-line and liquid level sensors from Introtek incorporate the latest generation MEC pulse-type ultrasonic circuitry HIGHLIGHTS N NEW ADU Series Sensor for non-standard soft tube sizes between 1⁄8" and 3⁄18" where standard AD9 housings are not available; can eliminate tooling costs for low volume requirements for some odd-sized tubes. N Compact design features integral INTROTEK CERTIFICATIONS expands the circuit’s functionality. N High EMI and RFI noise immunity. N Reliable pulse-type, non-invasive N Air detection threshold or bubble ntrotek 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 size can be set to our customer’s requirements. N Accommodates a wide range of tubing sizes. N Dry coupled; no coupling gel is required. N Accuracy is not affected by fluid or tubing color. control. Response times, time delays and other functions are programmable to specific requirements. TECHNOLOGY Introtek patented pulse-type ultrasound provides highly reliable, non-invasive air detection capabilities in critical applications where the safety of a patient or the integrity of a process is essential. Many of the variables which affect the accuracy of amplitude based or continuous wave ultrasound are greatly reduced if not eliminated by pulse-type technology. N Air bubble, air-in-line and liquid level sensing N Patient-connected medical devices, including: Apheresis Auto-transfusion Infusion pumps Perfusion-based “life • Heart-lung bypass • Dialysis • Cardiac assist pumps support” devices N Chromatography and separations technology N Immunoassay and diagnostic equipment N Liquid and chemical dispensing N Blood processin
