Abstract
Abstract A BOURDON TUBE PRESSURE GAUGE HAS ITS INSTRUMENT MOVEMENT MOUNTED BETWEEN A BOTTOM AND TOP PLATE WITH THE LATTER BEING PIVOTALLY MOUNTED ON THE SOCKET OF THE GAUGE AT A POINT SPACED FROM THE POINTER AXIS. THE TOP PLATE IS PROVIDED WITH A SLOT EXTENDING RADIALLY FROM THE PIVOTAL CONNECTION. A PIN IS PIVOTALLY MOUNTED IN A BORE IN THE SOCKET AND IS PROVIDED WITH AN ECCENTRIC WHICH MOVES WITHIN THE TOP PLATE SLOT SO THAT ACTUATION OF THE PIN EXTERNALLY OF THE SOCKET WILL ADJUST THE MOVEMENT WHILE THE FREE END OF THE BOURDON TUBE REMAINS STATIONARY.
