Abstract
The present invention provides apparatus for visually indicating the failure of a rupture disc comprised of an elongated hollow body member, a piston disposed in the body member which is moved therein by pressurized fluid pressure exerted thereon, and an elongated indicator pin which is pushed by the piston through an opening in the body when pressurized fluid causes the piston to be moved therein. The body member includes a pressurized fluid exhaust port which is opened by the movement of the piston. Pressurized fluid exhausted through the exhaust port can be vented to prevent abnormal rupture disk operation or it can be utilized to activate an alarm.
