A sensor for measuring the internal profile of a small diameter pipe in order to quantify internal corrosion. The sensor is based upon the high frequency eddy current technique. Eddy current data are converted to dimensional data of the pipe. A combination of local probes and global coils is applied to be sensitive to small corrosion pits while being able to cope with geometrical changes of the pipe and/or movements of the inspection tool.
