POSITION INDICATOR FOR DETERMINING THE RELATIVE POSITION AND/OR MOVEMENT OF DOWNHOLE TOOL COMPONENTS, AND METHOD THEREOF |
摘要 |
A magnetic sensor array is presented for a well apparatus for determining the position of at least one movable component with respect to a fixed component of a downhole tool. The array comprises at least one conductor member having a plurality of contact regions spaced apart at first intervals of at least a first length along a longitudinal axis of said at least one conductor member and a plurality of magnetic sensors, each one of which is operably coupled to one of said plurality of contact regions and actuatable by a magnetic field from a magnetic actuator. |
