Abstract

Instrument indicateur électromagnétique du type comprenant un solénoïde d'induction d'un champ électromagnétique et une lame mobile en matière ferromagnétique disposée dans le champ induit par la bobine et articulée par un axe qui pivote à l'encontre d'un ressort de rappel, cet axe étant relie à une aiguille indicatrice. Cet instrument est caractérisé en ce que la bobine 1 est montée sur un noyau 2 en matière ferromagnétique qui est continué à ses extrémités par des prolongements 3 et 4 en forme de plaque, dont les bords libres délimitent un entrefer 8 et en ce que la lame mobile 9, en matière ferromagnétique introduite partiellement dans cet entrefer, est constituée par un élément en forme de plaque sensiblement à périphérie en S. Cet instrument est destiné notamment à la mesure de l'intensité de courants électriques, continus ou alternatifs.
