Method for calibrating magnetic field sensor used in automotive industry, involves determining sensitivity of sensor based on difference of strengths of magnetic field applied to magnetic field probe and difference of response voltages

摘要

The magnetic fields (15) of different strengths are applied to a magnetic field probe (10) of the magnetic field sensor (1), and the response voltages are read out. The sensitivity of the magnetic field sensor is determined based on the difference of the magnetic field strengths and the difference of the response voltages. The desired field intensity of the permanent magnet is determined on the basis of the determined sensitivity.
