Air gauges are non-contact devices that utilize air pressure for measurement. They play a crucial role in ensuring precision and quality control in the manufacturing industry, from automotive to aerospace industries. They are particularly valuable for measuring delicate or easily deformable materials.

Air gages work well due to three main reasons: they are body-piloting type, use dual-opposing sensor method, and have a noncontact sensing component. These features are present in most air gage designs, including ID/OD air probe, air ring, and air length gages.

What is air gaging? The what, who, why, and where of air gaging.

The biggest trend we are seeing in the manufacturing industry is automating the inspection process using robots. According to a projection from ABI Research, the number of industrial robots sold in the U.S. will jump nearly 300% in less than a decade. 

Patented for manufacturing in 1943, historians document this tool has been in use for nearly a century.
