A measuring instrument for determining diametral values on a stationary machine part 10 is provided with at least three pairs of linear measuring sensors 11, 12 and 13 which measure the diameter at three angularly spaced locations on the circumference. A device connected thereto selects and calculates characteristic values, such as the maximum, mean, and minimum diameters and the out of roundness of the machine part. The instrument may be arranged to measure internal diameters. <IMAGE> |
