SEALED PRESSURE INDICATOR |
摘要 |
A pressure indicator (106) according to the present invention monitors the pressure of the fluid in a vessel (102). One embodiment of the present invention comprises a closed pressurized gas volume (210) behind a dimpled metal diaphragm (208). In normal operation, the force of the fluid pressure acting on the external surface of the diaphragm (208) to hold the diaphragm (208) in a concave geometry. In the event of a sufficient loss of fluid pressure, the force of the gas pressure acting on the internal surface of th e diaphragm (208) will overcome the force of the fluid pressure acting on the external surface of the diaphragm (208), thereby moving the diaphragm (208) into a convex geometry. A viewing window (110) disposed in the side of the vessel (102) can be used to view the pressure indicator (106) and determine the shape of the indicator diaphragm (208).
