Abstract

Un capteur de pression différentielle comprend un boîtier (10), un premier (2,0) et un deuxième (30) éléments de détection de pression, un premier (40) et un deuxième (50) passages d'introduction de pression et un élément de détermination de pression différentielle (60). Les éléments de détection (20, 30) de pression agissent pour détecter respectivement une première et une deuxième pressions. Les passages d'introduction de pression (40, 50) sont prévus pour introduire respectivement les pressions vers les éléments de détection de pression (20, 30). L'élément de détermination de pression différentielle (60) détermine une pression différentielle comme différence entre les première et deuxième pressions détectées par les éléments de détection (20, 30). Les éléments de détection de pression (20, 30) présentent les mêmes forme et taille et sont symétriquement agencés dans le boîtier (10) par rapport à une référence, de la même manière que les passages d'introduction de pression (40, 50) .
