How-To
Putting Air Gages to Work
In Part I of this article, we examined the history and fundamental principles of air gaging as well as the various styles of air gaging systems in use today. This discussion will focus on the components that comprise a typical air gaging system and how they work together. We also will address the most common air gaging applications used in industrial environments.

Air gages, past to present, either measure flow or back pressure. Integrated air gaging systems are comprised of these basic components: air regulator, amplifiers, tooling, setting masters, connectors, and accessories.
- Internal diameter (bore) measurement via air plugs
- External diameter measurement via air rings
- Taper — angle variation of tapered surfaces checked as difference of two diameters
- Flatness — air nozzle mounted within stationary platen, part moved across nozzle
- Groove Width — flat, blade-type air tools; also determines parallelism of groove faces
- Matching applications
