ABSTRACT:
An improved gas leakage indicating device of the type in which an electrical warning signal is generated. Electrically conductive material which is chemically reactive with the particular gas to be sensed comprises part of an electric circuit. The electrically conductive material is located proximate connections or seals in the gas vessels so that in the event of a leak the gas chemically reacts with the conductor. The subsequent destruction or degradation of the conductor breaks the electric circuit, thereby generating the appropriate warning signal.
