Abstract (en)
[origin: WO2009121352A2] The invention relates to a measuring apparatus for determining magnetic field strengths by way of a Hall probe (2), and to a method for the functional diagnosis of a Hall sensor device (1). The measuring apparatus comprises a sensor device (1) having a Hall probe (2) and according to the invention is characterized by an electrical diagnosis conductor (4) that is galvanically isolated from the Hall probe (2). A diagnosable Hall sensor device (1) and a method for the functional diagnosis of a Hall sensor (2) are created, by which permanent, comprehensive diagnosis of the sensor device (1) or of the Hall sensor (2) can be carried out. In particular, the Hall sensor (2) can be checked not only qualitatively for functional capability or failure, but also quantitatively with respect to correct calibration, and optionally an immediate correction or recalibration of the sensor (2) can take place. In this way, particularly measuring errors, for example due to a temperature drift or due to mechanical stresses of the sensor (2), can be eliminated.
