Abstract
A method for the hot measuring of a transverse size of a metal profile to obtain a diameter and/or a mean thickness includes providing power with a sinusoidal current having at least two frequencies, a transmission element having at least two sections distinct and spatially separated from each other and disposed along a nominal axis of feed of the metal profile, generating an electromagnetic field with a desired profile of the force lines, and detecting a signal relating to the variations of the electromagnetic field due to the passage of the metal profile through the sections of the transmission element using a reception element having one or more sections distinct and spatially separated from each other and disposed along the nominal axis in a position of the transmission element.
