BD8 / BD9 Integral Ultrasonic Air Bubble, Air-In-Line & Liquid Level Detection Sensors The BD8 / BD9 series air bubble detection sensors incorporate Introtek's BDF sensor and BD3 electronics technology into a compact integral package. The requirement for remote electronics is eliminated, which further increases immunity to EMI / RFI interference, while operating with fail-safe logic. Applications Medical Devices (patient connected) Blood Processing Equipment Immunoassay & Diagnostic Equipment Liquid & Chemical Dispensing Chromatography & Separations Technology Liquid Level Control & Monitoring

View Printer Friendly Version   Measurement Principle Introtek's patented pulse-type ultrasonic technology provides highly reliable, non-invasive air 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 integral design with BD3 circuitry Reliable pulse-type, non-invasive, ultrasonic technology Wide range of tubing sizes from 1/16" (1.6mm) up to 1.0" (25.4 mm), including 4mm OD Infusion Tubing Air detection threshold or sensitivity can be user specified Dry coupled / No coupling gel necessary High noise immunity to EMI / RFI Options LED indicator Reverse output logic Open collector output Custom OEM designs
