The Eddy Current measurement reliably recognizes and locates cracks on the roll surface. Changes in the roll texture and subsequent hardening are detected during the measuring process as well. Since the Eddy Current measuring sensor is integrated in the roll measuring system, measurements are carried out during grinding and therefore without delay.
Jul 11, 2014 More modern techniques use non-contact devices such as proximity sensors, lasers or LED micrometers. With these devices,the actual rubber roll surface can be measured, but since circular runout is a station by station measurement, the number of measurements across the roll must be specified,including the bearing surfaces.
