Abstract
Systems and methods described herein provide for pressure relief valve detection and monitoring. A valve assembly includes a striker and an indicator assembly separated by a diaphragm. The diaphragm may be elastically or permanently deformable. The striker may be connected to a relieve valve disk that releases in response to high fluid pressure at the valve. Movement of the striker may be detected by contact with the diaphragm or by sensors near the diaphragm, which may trigger the indicator assembly to provide an external indication of a valve opening.
