Air In-Line Sensors (Bubble Detectors)

Bubble Detection

Our design expertise and manufacturing capability in this highly specialised sector allows development of high specification products to meet the tight tolerances of our medical OEM customers.

We can supply sensors and systems for applications including volumetric infusion pumps, hemodialysis machines, blood collection and component separation instruments and cardio-pulmonary bypass systems.

Our ultrasonic air-in-line sensors and ultrasonic bubble detectors can be designed to suit a variety of plastic tubing, as commonly used in medical equipment. The quality of our designs and the high performance of our piezo materials mean that bubble sizes down to four microlitres in volume or just two millimetres in diameter, can be detected.

Integrated Air-In-Line Sensors

Ultrasonic air-in-line sensors / ultrasonic bubble detectors are available on their own or complete with integrated control electronics and / or additional integrated sensors. For example, the air-in-line sensor can be combined with optical sensors to detect that the housing is correctly closed, for fail-safe operation.

Standard Products

We have a range of air bubble sensors to suit a variety of applications. These sensors will detect the presence of air bubbles in flexible tubing for example in infusion lines. All the sensors ca be mounted in any orientation and are designed to be dry coupled to flexible tubing such as PVC or silicone. Our range covers a wide variety of tube sizes and are IP67 rated and RoHS compliant.
