Title (EN) ELECTROMAGNETIC DRIVER AND SENSOR
(FR) ENTRAINEMENT ELECTROMAGNETIQUE ET CAPTEUR
Abstract:
(EN) A shielded electromechanical device for use in a Coriolis type mass flowmeter for interconverting mechanical energy and electrical energy has a coil assembly (82) connected to its distal end, and a magnetic assembly (72) connected to its proximal end. The magnetic assembly is adapted to interact with the coil assembly. A shield assembly (70, 84) surrounds the coil and magnetic assemblies and is adapted to reduce the magnetic field exterior to said shield assembly.
(FR) Dispositif électromécanique protégé destiné à être utilisé dans un débitmètre massique du type Coriolis permettant l'interconversion de l'énergie mécanique et de l'énergie électrique possédant un jeu de bobinage (82) relié à son extrémité distale, et un ensemble magnétique (72) relié à son extrémité proximale. L'ensemble magnétique est adapté pour exercer une influence mutuelle avec le jeu de bobinage. Une protection (70, 84) entoure le jeu de bobinage et l'ensemble magnétique et est adaptée de façon à réduire le champ magnétique à l'extérieur de ladite protection.
