PRESSURE RELIEF DEVICE HAVING CONDUCTIVE TRACE SENSOR FORMED THEREON

Abstract: an over-pressure relief device includes a pressure relief member and a rupture indicator. the pressure relief member includes a central rupturable section and an outer flange section in surrounding relationship to the central section. the rupture indicator includes an electrically nonconductive substrate and an electrically conductive trace. the substrate is operatively associated with the outer flange section and includes a cantilevered tab that extends over and in spaced relation to a surface of the central section. the trace is located on the substrate and extends onto a portion of the tab. the trace defines an electrical circuit capable of conducting an electrical signal and operable to detect a process condition associated with the over-pressure relief device.
