FIELD: electricity.
SUBSTANCE: invention suggests break indicator (24) to be used in rupture disc assembly (12). Break indicator (24) contains non-conductive material having external sleeve ring portion (66) and internal section (68) connected to the external part by a pair of jumpers (70, 72). The circuit containing electric conductive segments (78, 80) is placed on the break indicator (24) and can be used for monitoring of rupture disc integrity (20). One electric conductive segment (78) is placed at the external sleeve ring portion (66), while the other electric conductive segment (80) passes through jumpers (70, 72) and internal section (68). When rupture disc (20) is broken one of jumpers (72) carrying electric conductive segment (80) is open thus breaking the circuit.
EFFECT: improvement of the indicator.
