LifeGuard® ultrasonic air bubble detectors feature proprietary swept frequency technology, making these ultrasonic sensors more reliable and accurate than those utilizing fixed frequency or pulse-type circuitry. Moog's ultrasonic bubble sensors offer the most flexibility in air bubble sensor sizes, with three standard configurations for common tubing sizes. Additionally, production performance equivalent (quick-turn) custom ultrasonic sensors for use with any tubing size are available utilizing in-house 3D printing capabilities. Features of LifeGuard Ultrasonic Air Bubble Detectors • ISO 13485:2003 quality service certification • Detectors maintain precise sensitivity without calibration • Extremely reliable swept-frequency technology prevents ultrasonic sensor performance from drifting with temperature, age or environmental conditions • Integrated self-test function provides 100% single fault coverage • Dry-couples to PVC, silicone and many other tubing types with thick, thin or reinforced walls • Output pulse width is proportional to bubble size — allowing user’s system to monitor subcritical bubbles • Chemically compatible with common medical grade cleaners • Vibration resistant • Wide temperature range stable • High reliability: > 1 M hours MTBF • Proven performance in life critical equipment • Low power consumption • RoHS compliant • Designed and manufactured in the United States
