Abstract

Capteur de pression, notamment pour la mesure d'une pression de fluide au sein d'un stockage, comprenant un corps (2) muni d'une zone (3) sensible à la pression, la zone (3) sensible étant déformable et destinée à être exposée à la pression à mesurer, le capteur comprenant en outre un organe (4) électronique de mesure de la contrainte ou pression subie par la zone (3) sensible, l'organe (4) électronique de mesure de la contrainte étant relié à la zone (3) sensible et étant configuré pour convertir cette contrainte mesurée en une valeur de pression et pour générer un signal de pression mesurée, caractérisé en ce qu'il comporte une chambre (5) contenant un fluide compressible interposée entre la zone (3) sensible et l'organe (4) électronique de mesure, c'est-à-dire que l'organe (4) électronique de mesure de la contrainte est relié à la zone (3) sensible via la chambre (5) contenant le fluide compressible
