Hall effect magnetic field sensor for producing Hall tension, has processing module comprising amplification stage for amplifying profit followed by output switching stage delivering exploitable value

摘要

The sensor (10) has a module measurement module (20) equipped with a Hall cell (40) delivering a Hall voltage signal. A processing module (30) processes the Hall voltage signal for delivering an exploitable value. The Hall cell comprises a resistive layer equipped with two pairs of ohmic contacts (HB, GD) that are coupled with switching units (50) reversing measurement and polarization contacts at a switching frequency. The processing module comprises an amplification stage (G1) for amplifying a profit followed by an output switching stage (C1) delivering the exploitable value.
