摘要： A leakage flux probe for non-destructive leakage flux-testing of bodies consisting of magnetizable material, in particular of pipes consisting of ferromagnetic steel, having a plurality of sensors disposed one behind the other in a straight line for detection of near-surface flaws in the body. In order to create a leakage flux probe for non-destructive leakage flux-testing of bodies consisting of magnetizable material, in particular of pipes consisting of ferromagnetic steel, which in a main testing direction has a broadened directional characteristic. At least two similar sensors are disposed and interconnected in a sensor package in a different angular orientation with respect to the main testing direction one above the other, one next to the other or one lying inside the other. The sensor packages disposed generally in a line one behind the other can be influenced individually by the generated leakage flux of an existing flaw. The individual sensors of the sensor package are spaced apart from each other by such a small spaced interval that the interconnected sensors of a sensor package are collectively influenced by the generated leakage flux of an existing flaw.
