Strain Measurement Device’s (SMD) standard bubble sensors can detect bubbles as small as 0.1 microliters, but its SMD engineers can create custom bubble detector solutions for any application.

Noninvasive ultrasonic bubble detectors are available for both air-in-line or liquid-in-line monitoring.

The company’s highly reliable bubble sensors and detectors include digital smart circuits that can be calibrated to precisely detect bubbles in almost any fluid and tubing material across a wide range of tubing sizes.

Its noninvasive bubble sensors can be designed for any tubing material, including steel, plastic, polyvinyl chloride (PVC), silicone, glass and fluoropolymers such as Teflon, polyethylene and nylon. Standard bubble sensor models are available for tubes as small as 1/16in outside diameter (OD) and as large as 1/2in OD. The company also offers custom bubble detectors for larger tubes.

For extremely accurate bubble detection, SMD regularly carries out bubble size testing and writes reports to be used as part of a customer’s US Food and Drug Administration’s (FDA) approval process. At its facilities, the company can generate bubbles as small as 0.5 microliters for testing sensors.

For many of SMD’s customers, the company also completes bubble size testing on shipped parts to ensure critical bubbles are detected and nuisance bubbles are ignored.
