Abstract: 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 the 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).
Abstract translation: 根据本发明的压力指示器（106）监测容器（102）中的流体的压力。 本发明的一个实施例包括在凹坑金属隔膜（208）后面的封闭的加压气体容积（210）。 在正常操作中，作用在隔膜（208）的外表面上的流体压力将隔膜（208）保持为凹形几何形状。 在流体压力的充分损失的情况下，作用在隔膜（208）的内表面上的气体压力的力将克服作用在隔膜（208）的外表面上的流体压力的力，从而移动 隔膜（208）变成凸起的几何形状。 设置在容器（102）侧面的观察窗（110）可用于观察压力指示器（106）并确定指示器隔膜（208）的形状。
