Abstract: Position finding system having a sensor unit and a transmitter unit. The sensor unit comprises a first RFID transponder reader unit, a first inductive detector unit, and an analysis unit connected to the RFID transponder reader unit and the inductive detector unit; the transmitter unit comprises an RFID transponder and a metallic material. The sensor unit is movable relative to the transmitter unit. The RFID transponder reader unit is configured for absolute position finding and outputs a first position value, and the inductive detector unit is configured for absolute position finding and outputs a second position value. The analysis unit is configured to determine, from the data acquired from the transmitter unit, an absolute position of the sensor unit from the first and second position values.

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.

Abstract: A read head with a sensor unit is provided, whereby the sensor unit has a first RFID transponder reader unit and an induction detector unit, and the read head has a longitudinal axis and can be moved along the longitudinal axis of a track, and an evaluation unit connected to the RFID transponder reader unit and to the induction detector unit is provided. The RFID transponder reader unit is set up for absolute position determination and outputs a first position value, and the induction detector unit is set up for absolute position determination and outputs a second position value, and whereby the evaluation unit is set up to determine an absolute position from the first position value and the second position value.
