Abstract

PURPOSE:To measure automatically the diameter of a cylindrical product in a simple way, by putting three relative displacement meters provided on a plane orthogonal to the axial core of an object to be measured close to said object to obtain the difference of displacement. CONSTITUTION:The relative displacement meters 1-3 are set in parallel to each other on a plane orthogonal to the axial core of an object 8 to be measured, and these meters are put close to the object 8. The outputs of these meters are amplified and supplied to a microprocessor 5 via an interface part 4 which performs an A/D conversion. The diameter R and the center coordinates (a), (b) of the circle of the object 8 are calculated from the relative displacement among the meters 1-3 and using the probe tip of the center meter 2 for the original point of the coordinates. These calculated values are supplied to a monitor TV6 and a printer 7. Thus the diameter of a cylindrical product is automatically measured in a simple way.
