Bubble Sensors and Air In-Line Sensors

Our highly reliable bubble sensors and air in line detectors include the latest in digital sensing technology that can be calibrated to precisely detect bubbles in almost any fluid and tubing material across a wide range of tubing sizes.

Noninvasive Bubble Sensors

Our noninvasive bubble sensors can be designed for any tubing material: steel, plastic (PVC, fluoropolymers including Teflon, polyethylene, nylon, etc.), silicone, glass, and others. These noncontact, standard bubble sensor models are available for tubes as small as 1/16" OD and as large as 1/2" OD. We also offer custom bubble detectors for larger tubes.

Ongoing Innovation in Bubble Sensors

Our newest bubble sensor product line (the AX1X Series) was redesigned from the ground up for medical device OEM users to maximize performance and minimize production costs. We took our 10+ years of experience designing and manufacturing ultrasonic bubble sensors for the medical device industry and used it to optimize and streamline every facet of the design. We have made design improvements such as miniaturizing our transducers to detect smaller bubbles and modernizing our production electronics and tooling. Our tools acquire real-time data from more than a dozen sensors simultaneously during our production testing processes allowing us to offer the best performance at some of the most affordable prices on the market.

Bubble Detector Equipment Testing and Reporting

Our company-owned and operated production facilities are equipped to perform bubble size testing as small as 0.5 microliters, with options for complete testing on 100% of shipped parts.  SMD also executes bubble size testing and report generation for FDA approval processes.
