Abstract
A sensing system for use with a subsea actuator has an actuator with a cylinder having a piston therein, and a piston rod extending outwardly of the cylinder, a magnetic member connected to or cooperative with an end of the piston rod, and a magnetic field sensor positioned over the magnetic member so as to sense magnetic field changes in relation to a movement of the magnetic member relative to the magnetic field sensor. A data acquisition system is cooperative with the magnetic field sensor for receiving a signal from the magnetic field sensor. A housing is positioned over the magnetic field sensor and over the magnetic member. The magnetic member moves through the housing in relation to a movement of the piston rod.
