The burst disc indicator allows quick notification when a rupture disc bursts. The B.D.I. utilizes a thin metallic strip located on the outlet side of a rupture disc. It acts as a closed electrical circuit until the mating rupture disc bursts. When the rupture disc bursts, the metallic strip is severed, disrupting the flow of current through the strip. An attached alarm monitor (the circuitry to which the metallic strip is connected) can then transmit a warning signal.
