Non-contact double sheet monitoring

Two OD displacement sensors determine the thickness of the sheet with an accuracy of ± 10 μm. This solution reliably detects double sheets and sheet thickness. The non-contact measurement method improves the cycle time and, consequently, the efficiency of the machine. An evaluation unit calculates the measuring signals and transfers the results to the control.
