Abstract
Method for measurement of the cross-section of an elongated element in wire or strip material production processes. The AC-resistance of the wire is related to the AC-frequency of a signal fed through the wire. The radius is found by relating a discontinuity in the resistance-to-frequency relation as where the skin-depth is equal to the radius.
