Abstract

Dispositif de mesure de pression fonctionnant en numérique. Ce dispositif comprend une première chambre soumise à la pression à mesurer, une seconde chambre soumise à une pression de référence et réunie à la première par une ouverture munie d'un clapet, un moyen de mesure de l'écart, en grandeur et en signe, entre les pressions qui règnent respectivement dans la première et la seconde chambres, ce moyen délivrant un signal électrique fonction dudit écart, un circuit de détection des instants où ledit écart atteint des valeurs déterminées, un moyen relié audit circuit et apte à commander le clapet, un compteur-décompteur, et un moyen d'affichage du nombre obtenu par ledit compteur-décompteur. Application à la réalisation de capteurs de pression.
