Title (EN) BOURDON TUBE PRESSURE GAUGE
(FR) MANOMETRE A TUBE DE BOURDON
Abstract:
(EN) A pressure gauge comprising a body (14) and a pressure sensing member consisting of a resiliently flexible curved tube (12) attached to said body (14) and having a fixed end (16) for communication with a fluid to enable pressure measurement, and a closed opposite end (18) freely movable by the fluid pressure relative to said body (14) and controlling a pressure indicator (20). Said gauge comprises at least one stop (36) arranged between the body (14) and the tube (12) for restricting the resiliency of the tube (12).
(FR) Ce manomètre comporte un corps (14), un organe capteur de pression constitué par un tube cintré (12) élastiquement déformable fixé audit corps (14) et comportant une extrémité fixe (16) de mise en communication avec un fluide en vue d'en mesurer la pression et une extrémité opposée (18) fermée libre de se déplacer par rapport audit corps (14) sous l'action de la pression du fluide et pilotant un indicateur de pression (20). Il comporte au moins une butée (36) de limitation de la déformation du tube (12), interposée entre le corps (14) et le tube (12).
