LifeGuard® Ultrasonic Air Bubble Detector
ACCURATE & NON-INVASIVE ULTRASONIC BUBBLE SENSORS
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
