MAGNETIC HEAD FOR A MAGNETIC DETECTOR FOR DETECTING METAL PARTICLES, AND MAGNETIC DETECTOR PROVIDED WITH SUCH A HEAD

摘要

Said magnetic head (11) for a magnetic detector for detecting metal particles in a hydraulic circuit comprises an axial body (14) internally comprising at least one magnet (15, 16), at least one first electrode (17, 18) defining an air gap region (E) located in the magnetic field created by the magnet, such that the circuit creates in the air gap a particle alignment zone and means for electrically connecting (C) the electrodes. The magnet is a diametrically magnetised magnet.
