A sensor for measuring displacement and time comprises a hollow body including a longitudinal axis. The hollow body comprises a wall including an inner surface and an outer surface, and a pathway defined by the inner surface. The sensor further comprises a solid body including an outer surface, the solid body configured to be received by the hollow body and travel through the pathway. The sensor further comprises a plurality of frangible wires, where each wire of the plurality of wires extends through a first opening in the wall, across the pathway, and through a second opening in the wall, and each wire is spaced apart by a distance in a direction generally parallel to the longitudinal axis of the hollow body.
