True Position Indicator
First Claim
1. A system for directly sensing a position of a movable part of a hydrocarbon drilling and production operation, the system comprising:
- a housing having a body with an inner cavity and a body wall with a wall thickness defined between an inner surface of the inner cavity and an outer surface of the body, the inner cavity further having a fluid flow path for hydrocarbon development fluids;
a moveable member located within the inner cavity, the moveable member having a set position;
a sensor assembly located within one of the body wall and the moveable member, the sensor assembly being positioned within a port; and
an indicator feature on the other of the body wall and the moveable member, the indicator feature sensable by the sensor assembly when the moveable member is in the set position.

Abstract
A system for directly sensing a position of a movable part of a hydrocarbon drilling and production includes a housing having a body with an inner cavity and a body wall with a wall thickness defined between an inner surface of the inner cavity and an outer surface of the body. The inner cavity has a fluid flow path for hydrocarbon development fluids. A moveable member is located within the inner cavity. A sensor assembly is located within one of the body wall and the moveable member, the sensor assembly being positioned within a port. An indicator feature is on the other of the body wall and the moveable member, the indicator feature sensable by the sensor assembly when the moveable member is in a set position.
