Abstract (en)
[origin: WO2015003190A2] The present disclosure relates to a monitor for a blowout preventer of a wellbore. The blowout preventer includes a housing, rams, and an actuator comprising a cylinder with a piston. The piston is operatively connectable with the ram and movable therewith. The monitor includes a monitor base operatively connectable to the cylinder (the monitor base having an interior side inside the cylinder and an exterior side outside the cylinder), an interior plate positionable inside the cylinder about the interior side of the base (the interior plate operatively connectable to the piston and movable therewith), an exterior plate positionable outside the cylinder about the exterior surface of the monitor base (the exterior plate coupled by magnets to the interior plate and rotatable therewith), and a trigger sensor operatively connectable about the monitor base and the exterior plate to detect rotation thereof whereby a position of the ram may be determined.
