CAPTEUR ELECTROMAGNETIQUE CYLINDRIQUE ET PROCEDE DE DETERMINATION SIMULTANEE DE DIFFERENTS PARAMETRES D'UNE CIBLE CYLINDRIQUE ASSOCIEE

摘要

The cylindrical electromagnetic sensor comprising at least one circular cross-section cylindrical coil (2) associated to a core (1) with high magnetic permeability, is characterized in that the core (1) is a cylinder having a circular cross section, in that the coil (2) is fixed to a side face of the core and comprises a symetry axis coaxial to the core face on which it is fixed, and in that the core (1) has a thickness (E) larger than the thickness (e) of the coil so that the magnetic field lines resulting from the excitation of the coil are substantially all of them included in the core.
