Introtek BDS Sensors are designed to work well with a wide range of tubing materials and sizes. When utilized with Introtek’s circuitry they provide the most reliable strap-on bubble detection. BDS sensors are typically used on tubing larger than one inch and can detect point level on containers up to four feet in diameter. ♦ BDS Strap-On sensor for larger diameter tubing and liquid level applications. ♦Non-invasive technology does not contact the fluid or require a break in the tubing. ♦Low cost, premium performance. ♦Wide range of sizes and mounting options. ♦Fastest air detection circuitry available. ♦Not affected by fluid color or tubing material. ♦High EMI and RFI noise immunity. ♦Custom manufactured systems for OEM applications available. TECHNOLOGY Introtek ultrasonic air bubble detectors and liquid level sensors utilize the characteristics of high-frequency acoustic energy to monitor tubing or vessels for the presence of air, air bubbles, foam, or liquid. A sensor containing piezoelectric crystals is placed in direct contact with the desired point of detection. Introtek air detection sensors and electronics emit pulses of ultrasonic energy, which are sent through tubing and normally received within a specified “window” of time. If air becomes present, the ultrasonic signal does not arrive within this “window” of time and a warning or dry signal is immediately transmitted. APPLICATIONS ♦Air bubble, air-in-line and liquid level sensing ♦Patient-connected medical devices, including: •Apheresis - • Heart-lung bypass •Auto-transfusion • Dialysis •Infusion pumps • Cardiac assist pumps •Perfusion-based “life support” devices ♦Immunoassay
