The invention relates to a leakage flux probe for non-destructive leakage flux-testing of bodies consisting of magnetisable material, in particular of pipes (1) consisting of ferromagnetic steel, having a plurality of sensors (5) disposed one behind the other in a straight line for detection of near-surface flaws (F1, F2, F3) in the body. In order to create a leakage flux probe for non-destructive leakage flux-testing of bodies consisting of magnetisable material, in particular of pipes consisting of ferromagnetic steel, which in a main testing direction has a broadened directional characteristic, it is proposed that at least two similar sensors (5, 5') are disposed and interconnected 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 as a sensor package (4), that the sensor packages (4) which are disposed one behind the other can be influenced individually by the generated leakage flux of an existing flaw and the individual sensors (5, 5') of the sensor package (4) are spaced apart from each other by such a small spaced interval that the interconnected sensors (5, 5') of a sensor package (4) are collectively influenced by the generated leakage flux of an existing flaw |
