Abstract

La présente invention concerne les capteurs de pressions différentielles. Le capteur se caractérise essentiellement par le fait qu'il comporte un noyau magnétique plongeant dans l'entrefer de deux bobines d'induction qui sont disposées dans un logement étanche. L'invention trouve une application particulièrement avantageuse dans les capteurs de pressions différentielles à variation de réluctance.
