Abstract: A scale element for an inductive position measuring device includes a substrate on which a graduation track is arranged. The graduation track is formed along a measuring direction from a periodic sequence of alternately arranged electrically conductive graduation regions and non-conductive graduation regions. The electrically conductive graduation regions are formed from a layer of electrically conductive material. At least one bore is arranged in the substrate for fastening the scale element to a machine part. The electrically conductive graduation regions have an opening, in which the electrically conductive material encloses the opening. In at least one of the electrically conductive graduation regions, the bore is arranged in the substrate through the opening.

Abstract: A sensing element for an inductive angle measuring device includes a first, a second, a third, and a fourth receiving conductive path. The second receiving conductive path extends over a second arc length, and the fourth receiving conductive path extends over a fourth arc length. The course of the first receiving conductive path and the third receiving conductive path is periodic along a first circular line. The course of the second receiving conductive path and the fourth receiving conductive path is periodic along a second circular line. The second receiving conductive path and the fourth receiving conductive path are arranged such that there is a first gap with a first gap length and a second gap with a second gap length between them in the circumferential direction. The first gap length and the second gap length are of different sizes, or the second arc length and the fourth arc length are of different sizes.

Abstract: A measuring device includes first and second component groups rotatable about an axis relative to each other. The first component group has a scanning component, having a first substrate, and the second component group has a scale component, having a second substrate and an angle scale. The measuring device can determine a relative angular position between the component groups. The measuring device has a passive sensor array having conductor track structures. The conductor track structures are applied on the first substrate by an additive process so that the sensor array determines a torsional load of the first substrate about the axis. Alternatively, the conductor track structures are applied on the second substrate by an additive process so that the sensor array determines a torsional load of the second substrate about the axis.

Abstract: An inductive position-measuring device includes a scanning element and a graduation element movable relative thereto along a direction. The scanning element has an excitation conductor, and first and second receiver tracks each having a receiver conductor, which extends along the direction according to first and second periodic patterns, respectively, over a length. A graduation track has graduation structures formed of ridges and gaps. The ridges have different widths, or the gaps have different depths or different widths, in the direction. The receiver conductors of the first and second receiver tracks are configured to generate first and second signals having first and second period lengths, respectively, wherein n times the first period length equals m times the second period length, with m and n being relatively prime, and n times the first period length and m times the second period length both being less than or equal to the length.
