Abstract
Embodiments of the invention disclose systems, apparatuses, and methods of measurement performed by pipe conveyed tools. In an embodiment, a system for evaluation of a well bore includes a drill string assembly comprising a plurality of pipe joints, a wired slip joint coupled to the plurality of drill pipe, the slip joint movable from a retracted position to an extended position to compensate for changes in length of the drill string, the extended position having a length greater than the retracted position; a sensor positioned in the slip joint, wherein the sensor detects a change in length of the slip joint and generates a signal representative of a position of the slip joint, and a communication system to transmit the signal from the slip joint to a surface processor.
