A burst indicator (24) for use in a rupture disc assembly (12) is provided. The burst indicator (24) comprises a non-electrically conductive material having an outer annular portion (66) and an inner section (68) joined to the outer portion by a pair of bridge features (70, 72). A circuit comprising electrically conductive segments (78, 80) is located on the burst indicator (24) and can be used to monitor the integrity of the rupture disc (20). One electrically conductive segment (78) is located on the outer annular portion (66), and another electrically conductive segment (80) extends across the bridge features (70, 72) and inner section (68). Upon rupture of the rupture disc (20), one of the bridge features (72) carrying an electrically conductive segment (80) severs thereby opening the circuit. |
