Abstract

Manomètre fondé sur l'utilisation d'une capsule anéroïde et destiné plus particulièrement aux radiosondes, dans lequel le déplacement relatif des membranes de la capsule anéroïde est transformé en une grandeur capacitive proportionnelle à la pression à mesurer et dans lequel les membranes de la capsule anéroïde sont réalisées en une matière isolante. Les plateaux opposés 21, 22 du condensateur sont fixés respectivement aux surfaces extérieures des deux membranes de matière isolante 11, 12 de la capsule anéroïde et la capacité C est mesurée entre ces plateaux 21, 22. Application : manometre, notamment pour radiosondes.
