Abstract:
    A method for positioning a reading position in radial pressure detection of piston ring includes carrying out said detection repeatedly till accurate value is obtained in order to decrease error caused by deformation of strain window to raise detection accuracy. In said method, reading position is position that radial pressure value is changed from small to big and then changed to small again in following course of moving piston ring downwards, the moving height is decreased in following increase of moving frequency for raising operation efficiency.
