Abstract

Dispositif pour mesurer une pression en deux points d'un écoulement fluidique, comprenant: - un bâti (10) formé de deux plaques (12, 14) comportant chacune deux faces planes, l'une extérieure (12a, 14a) et l'autre intérieure (12b, 14b), et dans lequel l'une des plaques (12) est percée d'une creusure (22) fermée par l'autre plaque (14) pour former ensemble deux ahmbres (28, 30) comportant deux parois (24, 14b) planes parallèles aux faces (12a, 14a) du bâti et une paroi latérale (26) formant son pourtour ainsi qu'un canal de restriction fluidique (32) reliant les chambres (28, 30) entre elles, et - des moyens (16) pour fournir une mesure de la pression dans chacune des chambres (28, 30). Afin d'améliorer la précision de la mesure, la paroi latérale (26) des chambres (28, 30) est perpendiculaire à ses deux parois planes (24, 14b) et est conformée de manière à ce que les chambres (28, 30) soient fusiformes.
