  • Publication number: 20050179429
    Abstract: In a method for the detection of local displacements and rotations, a sum signal and additionally a difference signal are formed from two separately generated signals of two transducer elements (W1, W2), which are spaced from each other, and subsequently the formed sum signal and the formed difference signal are OR-operated. A device for doubling the local frequency of moving incremental scales comprises an encoder (1a, 1b, 1c), a magnetically sensitive transducer (9, 13), and a signal conditioning stage (6a, 6b) electrically connected thereto. The transducer comprises at least two sensorially active functional groups synchronously using sensorially active groups or sub-groups (W1, W2) which are locally offset in relation to each other by a local phase ? in order to scan the moving scale, and the functional groups comprise means enabling at least two independent partial signals S1=V*sin(?t) and S2=?V*sin(?t)+?) to be produced.

    Abstract: The present invention relates to a method for checking or determining the installation air slot between an active sensor and an encoder, wherein the maximum size of the air slot (maximum air slot) which still ensures trouble-free operation of the sensor depends on the level of the supply voltage of the sensor at least within a range of said supply voltage, and which is more particularly characterized by the following method steps: reducing the supply voltage of the sensor to at least one value by which the maximum air slot is each time decreased by a desired test measure, and comparing the at least one test measure with a desired difference between the maximum air slot and the existing air slot by sensing a variation of the sensor output signal by the reduction of the supply voltage, as well as evaluating the comparison result by signaling and/or storing. A corresponding device is also described.
