<p>A Bourdon press. gauge has a Bourdon tube bent in an arc of a circle and connected through a capillary to a coupling tube. The flat-section Bourdon gauge has a two-part case and a connecting pipe on its back, to which the Bourdon tube is connected. The tube's free end is connected to the pointer mechanism. The press. gauge has a supporting plate (5) on its back wall (3), on which the pointer mechanism (19) and the Bourdon tube (14) are mounted. The Bourdon tube is bent into an arc of circle smaller than 170 deg. Its fixed end is connected through a capillary tube (15) to the connecting tube (4) at the back.</p> |
