ABSTRACT:
A reliable signaling device is provided which will allow an operator of a reactor vessel to ascertain when a leak has occurred in the reactor vessel rupture disc or diaphragm. The signaling device is actuated by pressure which escapes through a leak in the rupture disc. The signaling device makes the operator aware of when a rupture disc is leaking and thereby avoids a potential hazard of the reactor vessel exceeding its designed pressure rating. The signal device when modified may also be used in vacuum operations.
