Abstract (en)
[origin: WO2014095107A1] The invention relates to a sensor device (10) for detecting at least one rotational property of a rotating element (42), particularly for detecting a rotational speed of a compressor wheel (42) in an exhaust gas turbocharger, wherein the sensor device (10) comprises at least one magnetic field generator (14) for generating a magnetic field at the site of the rotating element (42) and at least one magnetic sensor (18) for detecting a magnetic field generated by eddy currents of the rotating element (42), wherein the sensor device (10) comprises at least one pole pin (16). The pole pin (16) is elongated at the end thereof facing the rotating element (42) and has a section which is not enclosed by the magnetic sensor (18). A coil (18) can be used as the magnetic sensor. The sensor can be placed in a blind bore (24) in the exhaust gas turbocharger casing as a plug probe.
