Abstract: The present invention relates to a sensor module for detecting unevenness of a surface, especially for detecting bulging and bowing of the pipe external surface. The sensor module comprises an arm assembly comprising an arm body having at least two ends, one or more surface contacting element mounted to at least one end of the arm body; a magnet assembly comprising at least one magnet to generate magnetic lines of force; and a magnetic sensor assembly comprising a magnetic sensor being assembled adjacent to the magnet for sensing changes in the magnetic lines of force in response to movement of the arm body. The invention also relates to an apparatus comprising the said sensor module and a method for detecting unevenness of a surface using the said sensor module.

Abstract: The invention relates to an apparatus and a method for inspecting an elongated tube-like object. The apparatus comprises a body (1, 2) for moving along the elongated tube-like object by clamping the object; and a sensor frame (15, 15b, 15c) supporting one or more sensors (20) for measuring a state indication property. One or more one or more body-to-sensor-frame connections (39, 40, 43, 72b, 72c) connect the sensor frame (15, 15b, 15c) to the body (1, 2), wherein the one or more body-to-sensor-frame connections (39, 40, 43, 72b, 72c) are arranged to allow an adjustable relative position between the sensor frame and the body, while the sensor frame can position itself with respect to the tube.
