  • Sensor for indicating a position or a change in position of a coupling element and method for operating the sensor
    Patent number: 9581425
    Abstract: Sensor having a primary coil, two secondary coils as well as an evaluator. An excitation signal may be applied to the primary coil. An output signal depending on a position of a coupling element may be induced in each secondary coil. An evaluator is configured to evaluate the output signals in order to evaluate a phase offset between the output signals. Further, the evaluator is configured to provide a sensor output signal indicating the position or change in position of the coupling element.
    Type: Grant
