Best Air Ring Gauge manufacturer , Faridabad ( Haryana). An air ring gauge, also known as an air gauge or an air plug gauge, is a precision measurement tool used in metrology (the science of measurement). It\'s designed to measure the dimensions of cylindrical or spherical objects with high accuracy. Working Principles : 1. Air Flow working : The gauge operates based on the principle of air flow and air pressure. When placed inside a cylindrical or spherical bore (hole) or over a shaft, the gauge detects variations in the air pressure caused by the dimensional differences between the gauge and the workpiece. 2. Probe and Sensors: Typically, an air ring gauge consists of a probe (which is the measuring element) and sensors. The probe is inserted into the part being measured. 3. Air Supply: A regulated air supply is connected to the gauge. The air flows through the gauge and exits at various points, depending on the gap between the probe and the workpiece. Advantages: High Accuracy: Air gauges can measure very small variations in dimensions, acording to micrometers. Non-contact Measurement: They don\'t require physical contact with the workpiece, reducing wear and damage. Inspection Time : Measurements can be taken quickly, especially useful in high-volume production environments. Applications: Quality Control: Used extensively in manufacturing to ensure precise dimensions of components. Production Monitoring: Helps maintain consistency in dimensions during mass production.
