An air gauge is a non-contact precision measuring instrument that uses the principle of pneumatics (the use of pressurized gas) to measure the dimensions of a workpiece. They are highly accurate and are commonly used in high-volume manufacturing environments.
Working Principle
The working principle of an air gauge is based on the relationship between airflow and back pressure. A constant stream of regulated, pressurized air is fed through a restricted nozzle in the measuring head of the gauge.
When the gauge is placed on a workpiece, the surface of the part acts as a variable restriction, limiting the escape of air from the nozzle.
If the part is smaller, there's less clearance, which restricts more airflow. This causes a buildup of back pressure.
If the part is larger, there's more clearance, which allows more airflow to escape. This results in less back pressure.
A calibrated sensor measures these changes in back pressure. The pressure reading is then converted into a dimensional measurement and displayed on a dial or digital readout
Applications
- AIR PLUG GAUGE: Used for measuring internal diameters of holes, bores, or cylinders. The plug is inserted into the workpiece, and jets on its surface measure the internal dimension.
- AIR RING GAUGE : Used for measuring external diameters of shafts, pins, or other cylindrical parts. The part is passed through the ring, and jets on the inner surface measure the outer dimension.
- AIR SNAP GAUGE : Similar to air rings, these are used for measuring external diameters but are designed in a C-shaped frame for quick, non-contact measurements on a variety of parts
