LifeGuard 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 and a factory adjustable Universal Air Bubble Detector for use with any tubing diameter from .100" to .450" (2.5 mm to 11.4 mm). All LifeGuard electronics are integrated into the sensor housing, ready to interface with the user's system.

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
• Sensor sensitivity can be changed at the factory with minor PCB modification
• Output pulse width is proportional to bubble size, allowing user's system to monitor sub-critical bubbles
• Power: 5 volt, <50 mA
