OPERATING PRINCIPLE
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.
APPLICATIONS
Determination of casing or completion of the open hole. ID identification to correlate with changes in clamping interface and tool combinations Simultaneous operation with other production registers 1 3/16 UN 12 top and bottom thread. Compatible with Sondex and OPTIONS Spring bow version for open hole Ultrawire™(UW) toolbus or memory toolbus (Mbus). Special heads according to customer specifications. Extended arms to increase the reach to the client’s liking.
