Position sensor, actuator-sensor device and method for inductive detection of a position

摘要

The position sensor (2) has a control- or processing unit (4) with an input (8) and an output (6), where the input and the output are coupled at a reference coil (R). The control- or processing unit is provided for delivery an output signal and for evaluating a vibration as an input signal indicating the position of a reference body. The vibration is generated by the current pulse in the reference coil. The output signal generates the current pulse in the reference coil. Independent claims are included for the following: (1) an actuator-sensor device with an actuator; and (2) a method for inductive detection of a position of a reference coil with respect to a reference body.
