Abstract

a. L'invention concerne un dispositif pour l'émission d'un signal électrique. b. Dispositif caractérisé en ce qu'il comporte un aimant qui, en présence d'une pièce conductrice située dans l'entrefer, engendre un flux magnétique à travers le générateur de Hall, la direction de ce flux étant opposée à la direction du flux magnétique du circuit magnétique principal. c. L'invention est applicable notamment à l'indication des vitesses angulaires et des angles.
