Abstract
A device for measuring the thickness of print products in a conveying flow includes a plate capacitor having a first plate and a second plate located on opposite sides of the print products. The plate capacitor is adapted to measure capacitance of the print products passing between the first plate and the second plate. A LC oscillator circuit is attached to the plate capacitor.
