  • Self-scanning apparatus having improved measuring range for measuring contour of a metallic body
    Patent number: 4288747
    Abstract: An apparatus for measuring the contour of a conductive object to be measured, includes eddy-current distance measuring means having a plurality of detection sensors which are arranged in a row at positions along a predetermined reference line, and the sensors are sequentially energized at a predetermined scanning period so as to self-scan the distance from the surface of the object and thereby to produce for each scanning cycle a contour output signal combining the outputs of all the sensors.
