  • Position-measuring device having a first measuring standard and at least two multiturn code disks
    Patent number: 8618466
    Abstract: A position-measuring device for measuring linear and/or angular positions includes a first measuring standard that has a first code track, with the aid of which consecutive position regions are cyclically measurable, and at least two multiturn code disks having second code tracks, via whose angular positions the currently measured position region of the first code track may be determined. The first measuring standard and the multiturn code disks are positioned such that the first code track and the second code tracks are scannable by a common scanning unit, through a first scanning window and second scanning windows, respectively.
