Abstract

APPAREILLAGE POUR LA DETECTION ET LA MESURE D'UNE PRESSION DE FLUIDE COMPRENANT UNE CHAMBRE DE PRESSION 10 DUDIT FLUIDE POSSEDANT UN DIAPHRAGME 18 MAGNETIQUE ET ELECTRIQUEMENT CONDUCTEUR PORTANT UN CONTACT 20 SE DEGAGEANT D'UN CONTACT FIXE 22 SOUS L'EFFET DE LA PRESSION REGNANT DANS LA CHAMBRE 10 ET SE TROUVANT EN CONTIGUITE AVEC LE CONTACT EN ABSENCE DE PRESSION OU SOUS L'EXCITATION D'UNE BOBINE MAGNETIQUE 30 COAGISSANTE. CELLE-CI EST RELIEE A UN CIRCUIT COMPRENANT UNE BASCULE HORODATEUSE 52, DONT LA SORTIE EST ELEVEE PENDANT QUE LES CONTACTS SONT OUVERTS ET FAIBLE DANS LE CAS CONTRAIRE. LE COEFFICIENT D'UTILISATION, RAPPORT DES TEMPS D'EXCITATION AUX TEMPS TOTAUX DONNE UNE MESURE DE LA PRESSION DETECTEE. L'INVENTION INTERESSE SURTOUT L'INDUSTRIE DES APPAREILS DE MESURE.
