The collet is spring loaded and follows the inside diameter of the pipe as it runs into the hole. It opens completely as it exits the pipe to enter the casing. Each arm operates as an independent unit exerting a constant radial force across any casing diameter. Shielded LVDT sensors within the main shaft accurately measure by induction the position of collars attached external to the shaft. The position of the collar blocks is related to the inner diameter of the tube.
