Abstract
Systems and methods described herein provide for pressure relief valve detection and monitoring. A valve assembly includes a valve body, having an inlet and an outlet, and a valve seat insert attached to the valve body between the inlet and the outlet. The valve body also includes an indicator assembly, a disk positioned within the valve seat insert; and a stem extending between the disk and the indicator assembly. The stem includes a magnet. A magnetic sensor is operable to identify proximity of the magnet. The valve seat insert is operable to release the disk when pressure at the inlet exceeds a threshold value. The disk, when released, moves the stem and magnet into a position that is detected by the magnetic sensor, and the indicator assembly indicates a valve opening event when the position is detected.
