An inline inspection tool of this disclosure includes at least one sensor arm () having a sensor head () located at its distal end (), the sensor head including an arched-shaped pipe contacting portion () between its forward and rearward ends (), the pipe contacting portion having a radius R and a width W; and at least one triaxial sensor element () having at least a portion located directly below the arched-shaped pipe contacting portion and having a width W, W&#x3c;W. During the tool's travel through a pipeline, contact of the sensor head with the pipe wall lies along a single line of travel substantially equal to the width W. Because of its shape, the sensor head better traces and maintains contact with the pipe wall to detect dents, wrinkles, weld intrusions, and other defects or anomalies in the pipe wall.
