Abstract

Le flottement de la partie diaphragme d'un détecteur à diaphragme dans le fluide de pressurisation libère le diaphragme des forces extérieures exercées par l'enceinte et abaisse les coûts de fabrication et de remplacement. Un diaphragme peut être protégé des contraintes extérieures en intercalant un canal entre le bord du diaphragme et la structure de fermeture et de support d'une enceinte. En étendant le canal et en incorporant un joint d'étanchéité adéquat, la structure de diaphragme devient changeable ou remplaçable. Le diaphragme remplaçable permet en outre d'utiliser une plus petite quantité de matériaux coûteux, et rend les réparations peu coûteuses.
