Air Plug Gauge Manufacturers in Delhi
An air plug gauge, also known as an air ring gauge or air plug, is a precision instrument used for measuring the diameter of a hole or the internal dimensions of a cylindrical or spherical object. It's commonly used in manufacturing and quality control processes where precise measurements are necessary.
How it functions:
Principle: Air plug gauges operate based on the principle of air flow. When inserted into a hole or cylinder, the gauge measures the air pressure required to maintain a seal between its outer surface and the inner surface of the object being measured. The pressure needed correlates to the size of the hole or cylinder.
Components: An air plug gauge typically consists of a cylindrical body with one end closed and the other end connected to a pressure gauge. The closed end has a precision-ground surface, while the open end usually has a threaded connection for attaching to a pressure source.
Measurement: To take a measurement, the air plug gauge is inserted into the hole or cylinder being measured. Air is then pumped into the gauge until it forms a tight seal. The pressure required to maintain this seal is displayed on the pressure gauge, which corresponds to the size of the hole or cylinder.
Accuracy: Air plug gauges are designed for high precision, often capable of measuring to very tight tolerances, typically within micrometers or even sub-micrometer ranges.
Applications: They're commonly used in industries such as automotive, aerospace, and machining, where precise measurements are critical for ensuring the proper fit and function of parts and components.
