  • Patent number: 8508243
    Abstract: The inductive incremental displacement sensor is characterized in that the first sensor unit and the second sensor unit each have a first inductive sensor and a second inductive sensor disposed at a distance from each other and that the first sensor unit and the second sensor unit deliver a switching signal relevant to a conductive region of the graduated track when the difference or the ratio of the detection signals from the inductive sensors allocated to the respective sensor unit as generated by the conductive region is less than a specifiable threshold. Furthermore, the invention relates to a method for determining the displacement of a first object relative to a second object as well as to an inductive sensor unit.

  • Patent number: 8242774
    Abstract: An incremental displacement transducer and method for determining a displacement of a first object relative to a second object having a scanning unit linked or to be linked with the first object for scanning a spacing or division track linked or to be linked with the second object having first areas and second areas arranged in alternating manner with a period length, the first areas having a first physical property and the second areas a second physical property differing therefrom, and where the scanning unit has a plurality of sensors for scanning the first areas and the second areas on the basis of the first and/or second physical property, and having an evaluation unit linked with the scanning unit for determining the displacement on the basis of measuring signals of the sensors.

  • Publication number: 20100188104
    Abstract: The present invention relates to an inductive incremental displacement sensor for determining a displacement of a first object relative to a second object, comprising at least one graduated track mountable on the first object and having periodically alternating conductive regions and insulating regions, and having at least one scanning unit mountable on the second object for scanning the graduated track with a first sensor unit and a second sensor unit, which are laterally spaced from each other by a distance d=n*(p/2)+q, wherein n is an integer or zero, p is the pitch of the graduated track and 0 is <|q|<p/2, and, in particular, q=0.25 p and comprising an evaluation unit for determining the displacement on the basis of switching signals delivered by the first sensor unit and the second sensor unit.
