Abstract

Eccentricity measurement device for non-ferromagnetic metal tubes, comprising a meter assembly comprising in turn a single probe associated with a system for positioning the probe and a system for translating the probe, so that said probe is capable of moving on the outer contour of the tube to be measured in a rotational direction with respect to the longitudinal axis of said tube, wherein said probe comprises a winding and at least one core of ferromagnetic material, so that in said winding the variation of inductance is measurable produced by a loop of lenz current in the wall of the tube to be measured, reducing the effect of the eddy currents of foucalt and being able to take the probe as many measurements as it is defined and; the corresponding method of measuring the eccentricity is also object of the present invention.
