operational procedures for a magnetfeldsensor basiegehu00f6rige arrangement for implementing this method

摘要

A method for operating a magnetic field sensor based on the tunnel magneto resistance effect, with the following measures:– the magnetic field sensor, which is designed as a magnetic-field-dependent resistor, is an ac voltage of predetermined basic frequency (f₀) and amplitude,– the response - signal of the resistance is in the case of a of the fundamental frequency (f₀) different frequency (f₁) measured and the resonance frequency (f₁) in a predetermined type of the fundamental frequency (f₀) dependent on.
