Zusammenfassung:A position measurement system including a material measure and a scanning device movable relative to one another with respect to a measurement direction. The material measure has a plurality of markings which are arranged in a row with respect to the measurement direction, wherein the scanning device includes a transmitter winding arrangement. Multiple receiver coils are provided which are arranged in a row with respect to the measurement direction. The inductive coupling between the transmitter winding arrangement and the receiver coils is a function of the position of the scanning device with respect to the material measure. The transmitter winding arrangement defines multiple separate transmitter areas which are arranged in a row with respect to the measurement direction. A maximum of one single receiver coil is situated in each of the transmitter areas. At least one switching means is provided via which the two adjacent receiver coils are differentially interconnectable.
