Air gauging modules are high-precision, non-contact measuring systems that utilize compressed air to assess dimensional features such as diameters, thicknesses, and roundness. These modules work on the principle of back pressure: air is directed through a nozzle toward the surface being measured, and changes in distance affect the air pressure, which is then converted into a dimensional reading. Air gauging is especially effective for measuring tight tolerances in internal bores and complex geometries where traditional contact gauges may be impractical. Widely used in automotive, aerospace, and high-precision manufacturing, air gauging modules offer fast, repeatable, and highly accurate measurements, making them ideal for in-line inspection and quality control.
