Proving Ring, Automation Grade : Automatic

The Proving Ring is a precision mechanical device widely used in material testing laboratories, engineering institutions, and industrial quality control units for measuring compression loads and calibrating testing machines. Its core principle relies on the elastic deformation of the ring under load, which is then measured by a highly sensitive dial gauge to determine the applied force accurately.

Manufactured from special steel or forged alloy steel, each proving ring undergoes heat treatment and precision machining to ensure minimal deformation, high stability, and repeatable results over long-term usage. The dial gauge attached to the proving ring typically offers a sensitivity of 0.002 mm per division, enabling detection of even minute changes in load.

Proving rings are available in a wide range of capacities, typically from 1 kN to 3000 kN, making them suitable for light to heavy-duty testing. The supplied calibration chart allows users to directly convert dial readings into applied loads with high accuracy. For added protection, each proving ring is individually packed in a polished wooden box, ensuring safe storage and transportation.

Designed for reliability and longevity, the proving ring is a must-have instrument for precision measurement, enabling engineers, researchers, and quality control professionals to perform accurate load measurements and machine calibrations efficiently.
