    摘要: A sensor device for acquiring at least one rotational property of a rotating element, particularly a rotational speed of a compressor wheel of an exhaust-gas turbocharger, includes at least one magnetic field generator for generating a magnetic field at the location of the rotating element, at least one magnetic sensor, e.g., a coil, for acquiring a magnetic field generated by eddy currents of the rotating element, and at least one pole pin. The pole pin is elongated at its end facing the rotating element and includes a section that is not enclosed by the magnetic sensor. The sensor can be installed as a plug sensor in a blind-end bore in the housing of the exhaust-gas turbocharger.

    摘要: A reciprocating piston internal combustion engine includes: a sensor system on a gas exchange valve which has a valve head situated at a first end of a valve stem; a lever element which engages at a second end of the valve stem and which is designed to actuate the gas exchange valve by displacing the valve head; a detection element which, upon actuation of the gas exchange valve, is displaced along a displacement path; and a sensor device configured to ascertain a position of the detection element. The sensor device is situated in such a way that the detection element, during a displacement along a portion of the displacement path, moves predominantly in a movement toward the sensor device or away from the same, thereby providing a measurement of valve timing of the gas exchange valve.
