| 20090241361 | Handheld diameter gage - A handheld device used to measure and display the average inner or outer diameter of cylindrical or nearly cylindrical parts. A wheel of a known radius rolls along the surface of a part along a path that is parallel to the edge of the part. The rotation angle of the wheel is counted to determine the length traveled by the wheel. A clip is placed onto the edge of the part in order to trigger the beginning and ending of wheel rotation counting. The average diameter of the part is equal to the wheel radius multiplied by the wheel rotation angle in radians. The average diameter of the part is displayed on either a mechanical display or an electronic display. | 10-01-2009 |
