A device for measuring a magnetic field gradient which the errors of impact and misalignments are minimized.

摘要

The device for measuring gradient comprises a magnetic field gradient sensor associated with electronic circuits, the sensor comprising a single saturable magnetic core (11) placed on a support and two windings (12, 13) wound in series on the support and around the magnetic core and used both for the excitation of the magnetic core and for the detection of the magnetic field gradient. Application to the detection of ferromagnetic objects. IMAGE
