Abstract
A contactless system for measuring centricity and diameter includes an optical measuring device for determining the external diameter and the position of a cable on an optical, perpendicular plane that runs transversally to the central axis Z of a measuring device. The cable has a conductor and a jacket that insulates the conductor and is pulled through the measuring device along the central axis Z. The system also includes an inductive measuring coil device for determining the position of the conductor on an inductive measuring plane, which is likewise perpendicular and runs transversally to the central axis Z of the measuring device. A correlation device correlate the position of the cable, determined by the optical measuring device with the position of the conductor calculated by the inductive measuring coil device and calculates the centricity of the conductor in the jacket from the correlation.
