Downhole tool sensor guard

A system for covering a sensitive component in a downhole string, comprising:

• a sub section in the downhole string including a longitudinal axis and a reduced diameter portion along the longitudinal axis;
• a first guard element positioned within the reduced diameter portion, the first guard element comprising a first coupling extension extending radially from an inner surface of the first guard element, the first coupling extension comprising a threaded hole, the threaded hole at least partially parallel to the longitudinal axis;
• a second guard element the second guard element comprising a second coupling extension extending radially from an inner surface of the second guard element, the second coupling extension comprising a hole;
• a mounting section formed in a reduced diameter portion of the sub section, the mounting section including an aperture separated by walls;
• and
• a fastener positioned within the pocket, extending through the hole in the second coupling extension and the aperture and engaging the first coupling extension.

A system for covering a sensitive component in a downhole string, comprising:

• a sub section in the downhole string including a longitudinal axis and a reduced diameter portion along the longitudinal axis;
• a guard element, positioned within the reduced diameter portion comprising at least one pocket and at least one coupling extension, the at least one coupling extension extending radially from an inner surface of the guard element, the at least one coupling extension including a hole;
• a mounting section formed in the reduced diameter portion of the sub section, the mounting section including an aperture separated by walls;
• a locking element extending axially through the aperture, the locking element including a threaded hole at least partially parallel to the longitudinal axis;
• and
• a fastener positioned within the pocket, extending through the hole in the at least one coupling extension, through the aperture and into the threaded hole of the locking element.

A method for covering a sensitive component in a downhole string, comprising:

• positioning the sensitive component within a reduced diameter portion of the downhole string;
• covering at least a portion of the sensitive component via a guard element, the guard element being arranged, at least partially, within the reduced diameter portion, the guard element having at least one pocket and at least one coupling extension, the at least one coupling extension extending radially into the reduced diameter portion from an inner surface of the guard element;
• positioning the at least one coupling extension proximate to an aperture of a mounting section, the aperture receiving a locking element;
• fastening the at least one coupling extension to the locking element via a fastener extending through the at least one coupling extension and a threaded hole of the locking element, the fastener being arranged within the pocket.
