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. BD8/BD9 Series Integral Sensors The BD8/BD9 integral sensors combine BD3 electronics with a free-entry sensor head for air bubble, air-in-line and liquid level sensing. HIGHLIGHTS N Non-invasive technology does not contact the fluid or require a break in the tubing. N Integral design facilitates integration into user’s ntrotek BD8/BD9 Integral sensors combine BD3 electronics with a free-entry sensor head. Constructed of soft polyurethane, the BD8 is recommended for rigid tubing. The rigid epoxy or ABS plastic BD9 is recommended for flexible tubing. product design and minimizes connections. N Fastest air bubble detection INTROTEK circuitry available. CERTIFICATIONS N No coupling agents required. N Low cost, premium performance. N Low power consumption. N 5, 12 or 24 VDC operation. N Reliable surface mount components. N Built in self-test and fail-safe logic. N High EMI and RFI noise immunity. N Not affected by color of fluid. N Can be used by a wide range of rigid and soft tubing. N Custom manufactured systems are available. N Air detection threshold or bubble size can be user-specified. TECHNOLOGY Introtek air bubble detectors and liquid level sensors utilize high-frequency acoustic energy to monitor tubing or vessels for the presence of air, air bubbles, foam or liquid. The sensor’s piezoelectric crystals are placed in direct contact with the desired point of detection. Air detection sensors and electronics emit pulses of ultrasonic energy which are sent through tubing and returned within a specified “window” of time. If air is present, the ultrasonic signal does not arrive within this “window” of time and a warning or dry signal is immediately transmitted. APPLICATIONS 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 Immunoassay and diagnostic equipment N Liquid and chemical dispensing N Blood processing equipment
