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.

First claim

1 - 45 . (canceled)

46 . 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 to take wellsite measurements and the downhole tool positionable in a wellbore; and electronics positionable in the movable component, the electronics to electrically connect to the sensor to receive the wellsite measurements from the sensor, the wellsite measurements usable to determine wellsite parameters.

47 . The sensor assembly of claim 46 , wherein the sensor comprises a position sensor to communicate with a reference positionable in the tool body of the downhole tool.

48 . The sensor assembly of claim 46 , wherein the sensor comprises a wear sensor positionable about a surface of the movable component.

49 . The sensor assembly of claim 46 , further comprising seals positioned about the sensor.

50 . The sensor assembly of claim 46 , further comprising a chassis to be carried by the movable component, the chassis comprising a sidewall with an electronics chamber to receive the electronics therein.

51 . The sensor assembly of claim 50 , further comprising a plug positionable about an opening of the chassis.

52 . The sensor assembly of claim 50 , further comprising a bracket to secure the chassis to the movable component.

53 . The sensor assembly of claim 50 , further comprising a disc to couple to the chassis, the sensor comprising a position sensor to be carried by the disc.

54 . The sensor assembly of claim 46 , wherein the electronics are positioned on an electronics board.

55 . A downhole tool, comprising:
a tool body; and a movable component movably positionable about the tool body, the movable component carrying a sensor to take wellsite measurements, the movable component housing electronics electrically connected to the sensor to receive the wellsite measurements from the sensor, wherein the wellsite measurements are usable to determine wellsite parameters.

56 . The downhole tool of claim 55 , wherein the sensor comprises a position sensor to communicate with a reference positioned in the tool body.

57 . The downhole tool of claim 55 , wherein the sensor comprises a wear sensor positioned about a surface of the movable component.

58 . The downhole tool of claim 55 , further comprising a chassis carried by the movable component, the chassis comprising a sidewall with an electronics chamber to receive the electronics therein.

59 . The downhole tool of claim 58 , further comprising a plug positioned about an opening of the chassis and a bracket to secure the chassis to the movable component.

60 . The downhole tool of claim 58 , further comprising a disc coupled to the chassis, the sensor comprising a position sensor carried by the disc.

61 . A method, comprising:
deploying a downhole tool with a sensor assembly into a wellbore, the sensor assembly comprising a sensor carried on a moveable component of the downhole tool, the moveable component positionable about a tool body of the downhole tool, the sensor assembly further comprising electronics housed within the movable component and to receive wellsite measurements from the sensor; performing a wellsite measurement using the sensor; and using the wellsite measurement to determine a wellsite parameter.

62 . The method of claim 61 , further comprising using the sensor and a reference positioned in the tool body to detect a position of the movable component.

63 . The method of claim 62 , further comprising moving the movable component about the tool body.

64 . The method of claim 61 , further comprising using the sensor to detect wear, the sensor positioned about a surface of the movable component.

65 . The method of claim 64 , wherein the sensor comprises a core having multiple conductors.
