G01V 1/46
E21B 12/02
E21B 47/09

Abstract:

Some embodiments include a sensor assembly comprising a sensor to be carried by a movable component movably positionable about a tool body of a downhole tool. The sensor is to take wellsite measurements and the downhole tool is positionable in a wellbore. The sensor assembly further includes electronics positionable in the movable component. The electronics are to electrically connect to the sensor to receive the wellsite measurements from the sensor, and the wellsite measurements are usable to determine wellsite parameters.

International Classification:

G01N 27/20

Abstract:

A sensor assembly for a downhole tool including a tool body and a movable component movably positionable about the tool body is disclosed. The sensor assembly may include a wear sensor and/or a position sensor. The wear sensor may include a core with conductors at various depths to send a signal, whereby, upon wear of the core, a change in the signal at the depth of the wear is detectable. The position sensor may be carried by the movable component, and may be used with references comprising magnets distributed about the tool body. The position sensor includes magnets having polarity responsive to polarity of the references whereby a position of the movable component is determined. The sensor assembly may also include a chassis housing electronics coupled to the position sensor and/or the wear sensor.
