Tell tale device for a pressure vessel

A post activation device to indicate that pressure the existed within a pressure vessel just prior to the opening of the pressure vessel and the resulting loss of pressurization, having a diaphragm, plug or piston (62, 130, 160, 330) capable of rupturing, moving or deforming in response to a pressur...

More Information
Summary:A post activation device to indicate that pressure the existed within a pressure vessel just prior to the opening of the pressure vessel and the resulting loss of pressurization, having a diaphragm, plug or piston (62, 130, 160, 330) capable of rupturing, moving or deforming in response to a pressure differential thereacross above one or more low limit values and for providing an indication of the pressure within the pressure vessel just prior to its being opened, and a support member (70), within the pressure vessel for supporting the diaphragm, plug or piston means.
