Abstract
A sensor for use in magnetostrictive testing of a structure. The sensor has a thin ferromagnetic strip with a series of parallel crimps across its width. A first wire coil is wrapped around the width of the strip and along its entire length, such that portions of wire that cross the bottom surface of the strip are located inside the crimps, and portions of wire that are wrapped across the top surface of the strip are between the crimps. The sensor further has a second coil wrapped around the length of the strip, or for pipeline applications, around the pipeline.
