Product details
Air Plug Gauges and Pneumatic Setting Rings are precision tools used in metrology, especially for checking internal dimensions (like bore diameters) with high accuracy and repeatability. Here’s a quick breakdown: 1. Air Plug Gauges: Purpose: Used to measure internal diameters of bores with high precision. Working Principle: Based on the air displacement principle. Compressed air flows through jets on the plug; changes in back pressure (caused by proximity to the bore surface) indicate size deviations. Types: 2-jet and 3-jet configurations (depending on number of measuring points). Advantages: Non-contact measurement (reduces wear). High precision and repeatability. Ideal for production environments. Applications: Common in automotive, aerospace, and precision manufacturing. 2. Pneumatic Setting Rings: Purpose: Used to calibrate or set the air plug gauges. Made of: High-grade steel or ceramic for dimensional stability. Function: They simulate the bore size that needs to be measured and help in setting the zero/reference point for the air gauge. Types: Master Setting Rings (for zero setting). Check Rings (for span or second-point verification).
