Abstract
Method to measure the variations in section of a hot rolled bar (12) as it is fed, the method including the generation of a variable frequency magnetic field by at least a generator device (14) defining an inner space (214) for the transit of the bar (12), the variations in section of the bar (12) in transit being measured by a receiver device (15) suitable to monitor the perturbations induced on the magnetic field by the variations in the area of section of the bar (12) in transit. The receiver device (15) is arranged coaxial and inside the generator device (14) and defines inside the same a surface for the transit of the bar. The (12) has a transverse section of (A.sub.S '), and the value ('f.sub.0 ') of the frequency of the magnetic field generated by the generator device (14) is suitable to minimize the influence of the real temperature of the bar (12) on the measurement.
