Fowler Sylvac Air Gage Measurement

The Fowler Sylvac Air Gage Measurement system is a high-precision, non-contact measuring solution designed to evaluate internal and external dimensions. It uses air jets and back-pressure technology to detect dimensional variations with exceptional repeatability and resolution. These systems are ideal for applications demanding consistent, high-speed inspection in production environments.

Air gaging uses compressed air that flows through calibrated nozzles positioned inside or outside a part. As the distance between the nozzle and the surface changes, so does the air back-pressure. This change is then converted into an accurate dimensional reading. Because there’s no mechanical contact, the process reduces wear and the risk of part damage.

Air gages are ideal for measuring diameters, taper, out-of-roundness, squareness, and straightness—particularly in bores or shafts. They are frequently used in the automotive, aerospace, and medical device sectors for quality control where high throughput and repeatability are required.

Compared to traditional contact gaging, the Fowler Sylvac Air Gage offers faster response times, reduced maintenance due to non-contact operation, and higher sensitivity in detecting minor dimensional changes. It also adapts easily to automated systems and provides real-time feedback.

Two primary display options are available: the D70A, a compact, plug-and-play unit for standard air gage inputs, and the D400S, a multifunctional touchscreen unit capable of displaying multiple values, combining input types, and handling up to 99 instruments.

Yes. The D400S unit allows users to measure multiple dimensions simultaneously and display results such as MIN, MAX, and DELTA for each. It’s capable of handling complex inspection routines involving several measurement channels on a single or multiple parts.

Absolutely. Both the D70A and D400S display units are designed to work with air gages from all major brands. The M-BUS Air Module acts as a universal bridge. This makes integration with your existing gaging setup seamless.

Willrich Precision provides comprehensive support materials, including the SYL1608-AIR-GAGES_Leaflet_EN_WEB, which outlines key features, specifications, and usage instructions. In addition, customers have direct access to expert guidance from Willrich’s metrology specialists to address technical questions and setup needs.

Routine maintenance typically involves cleaning the air jets, verifying calibration, and checking air filters for contaminants. Since the system is contact-free, physical wear is minimal. This helps extend the life of the measuring components and preserves accuracy over time.

These systems offer very high resolution and repeatability, with measurement uncertainty often in the micron range or better. Accuracy depends on factors such as air pressure, gage design, and the application setup. Proper calibration and setup are key to maintaining consistent results.
