Abstract
A capacitive pressure relief rupture disc monitor for use in detecting the rupture of an electrically conductive rupture disc installed in a pressure relief vent includes a flat metal loop positioned in spaced relation to the rupture disc and forming a capacitor therewith. A capacitance sensor is connected to the disc and the loop and is operative to generate an output signal in response to a selected change in the capacitance between the loop and the disc as a result of movement of portions of the disc during rupture thereof. The output signal from the capacitance sensor is operative to trigger an alarm to thereby indicate the rupture of the disc.
