Inductive position-measuring device for absolute position determination
Abstract:
An inductive position-measuring device for absolute position determination includes a scale having a first measuring graduation extending in a measurement direction and a second measuring graduation disposed opposite to the first measuring graduation and extending parallel thereto. A scanner is disposed in a gap between the first measuring graduation and the second measuring graduation. The scanner is displaceable relative to the scale in the measurement direction for purposes of position measurement. The scanner includes a first coil arrangement for scanning the first measuring graduation and generating a first position-dependent scanning signal, and a second coil arrangement, disposed opposite to the first coil arrangement, for scanning the second measuring graduation and generating a second position-dependent scanning signal. At least one intermediate layer of soft magnetic material disposed between the first coil arrangement and the second coil arrangement.
