Abstract
A Bourdon tube apparatus is provided for monitoring the pressure of a fluid pressure source. The output of the Bourdon tube is translated into a curvilinear motion which is transmitted to a linearly movable actuator valve or indicator. To enhance the force output linear response or linear output of the Bourdon tube actuator, an abutment block is provided which contacts one or more turns of the Bourdon tube adjacent its closed end to prevent expansion movement of the Bourdon tube in a direction opposite to the desired linear output movement. The Bourdon tube is mounted for calibrational purposes by having its open end connected by a flexible pipe to a support post which is rotationally mounted for movement about its longitudinal axis and defines a fluid conduit connection between the pressure source being monitored and the open end of the Bourdon tube. Angular rotation of the support post will effect the stressing or unstressing of the turns of the Bourdon tube to permit calibration of the linear output movement to the fluid pressure being monitored.
