Abstract

Transducteur de pressions de fluide, du type consistant en une capsule parfaitement étanche comportant un tube en soufflet et deux bases opposées, respectivement fixée sur un support et reliée à un index, ou organe analogue, permettant d'indiquer la pression du milieu fluide dans lequel est immergée la capsule Ce transducteur est caractérisé en ce que la capsule 10 est constituée par une enveloppe en matière plastique flexible en forme de soufflet à tube plissé de paroi mince, contenant un gaz (par exemple de l'air), l'élasticité du soufflet formé par le tube 12 de la capsule 10 étant négligeable par rapport à l'élasticité du gaz contenu. Ce transducteur est destiné notamment aux manomètres.
