“…We noticed that the flaw signal from the radial sensor was, in general, about two to three times as large as the corresponding (for the same exciting field) axial signal. This is partly due to the fact that the sensor is much closer to the wall of the tube [3]. Flaw fields were successfully measured at different frequencies by small sensors in the presence of a uniform exciting field.…”

“…A number of sensors are needed to span the inner perimeter of the tube. Sensors must be oriented to measure primarily the axial (paralleI to tube axis) and radial (perpendicular to tube axis) magnetic field components [3]. The computer model requires that twenty five frequencies be used.…”
