Eddy current pipeline inspection device and method |
摘要 |
A pipeline inspection vehicle which can be towed through a pipeline via a cable. The vehicle includes a power unit, a master processor module, and a coil which generates an eddy current field which passes along the pipe. The resultant field is detected by a master sensor ring and slave sensor ring. Information on an amplitude and phase of the detected field together with vehicle orientation information is sent to a base station which has a computer. A distance encoder also is provided to assist in locating the position of any detected faults.
