Abstract

See full text

A position-measuring device includes a graduation carrier which is non-rotatably connectable to a shaft and has a measuring graduation that is disposed radially about an axis of rotation of the shaft in a mounted state of the graduation carrier. A first scanner is configured to generate position signals by scanning the measuring graduation. A position-processor is configured to process the position signals into absolute, digital position values. An interface is configured to communicate with subsequent electronics. A second scanner is configured to generate measurement signals that are dependent on a position of a machine part by scanning a measurement target on the machine part. An analyzer is configured to process the measurement signals into a measurement value indicative of a position and/or a change in the position of the measurement target relative to the second scanner, and to output the measurement value to the interface.
