LifeGuard Ultrasonic Air Bubble Detector

ACCURATE AND NON-INVASIVE ULTRASONIC AIR-IN-LINE SENSORSLifeGuard Ultrasonic Air Bubble Detectors

LifeGuard ultrasonic air bubble detectors feature proprietary swept frequency technology, making these sensors more reliable and accurate than those utilizing fixed frequency or pulse-type circuitry.

LifeGuard air-in-line 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 sensors for use with any tubing size are available utilizing in-house 3D printing capabilities.

Features of all LifeGuard Air Bubble Detectors

  • Detectors maintain precise sensitivity without calibration
  • Extremely reliable swept-frequency technology prevents 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
