Abstract
PURPOSE: To accurately measure the outer diameter of a member having a circular shape in section, using two detectors of a non-contact type, by comparing the output corresponding to a change in the gaps between the peripheral surface of said member and the pointed ends of said detectors, and the output of a master the dimensions of which is know.
