A method for computer-aided sheet running control in a sheet-fed printing machine includes, during a printing operation, using a measuring sensor to detect a printed sheet in the printing machine and using an activation sensor to initiate measuring performed by the measuring sensor by emitting an activation signal. The activation sensor is mechanically fixedly installed without adjustment, and temporal deviations of the activation signal are determined and compensated. A system for computer-aided sheet running control in a sheet-fed printing machine is also provided.

Method and system for improved sheet running control in a sheet-fed printing machine

A sensor and a method for detecting a position of the sensor relative to a guide surface, comprising a housing and an electronic analysis device which outputs measurement values for the position of the guide surface on the basis of the measurement signals. The sensor contains an ultrasonic transducer array, each of the two outer ends of which is additionally equipped with a respective reference ultrasonic transducer and a respective reflector surface flush with the reference piezo disc at a distance from the base side, said ultrasonic transducers and reflector surfaces being inclined by 45&#xb0; relative to the base side and pointing towards one another, thus forming a reference measurement path with a known length between the two reference ultrasonic transducers. In the method for detecting the relative position, the measurement values are corrected with respect to environmental influences by measurements in a reference path.
