Abstract: A coiled tubing apparatus is described for use in wellbore operations. The apparatus includes a coiled tubing strand that may be deployed into a wellbore to convey a tool to a subterranean location. A signal cable extends through the coiled tubing strand to facilitate communication between a data acquisition unit at a surface location and the subterranean tool. Upper and lower detector elements are operably associated with the signal cable to detect forces applied to the signal cable at lower and upper ends of the signal cable. The operator may employ forces to adopt corrective measures to ensure the signal cable does not become damaged or loose communication with either the downhole tool or the data acquisition unit. Since the coiled tubing strand and the signal cable may experience elongation at different rates, forces are applied to the signal cable that could jeopardize the wellbore operation if not managed.
