Diffuse flow probe for non-destructive diffuse flow testing of bodies made from magnetisable material

摘要

The leakage flux probe comprises multiple sensors (5,5',5'') arranged rectilinearly one behind the other for the detection of near-surface flaws in the body. Two identical sensors are arranged and interconnected one above the other in different angular orientation, one next to the other or one lying inside the other as a sensor package (4). The individual sensors of the sensor package have a small distance from each another, such that the interconnected sensors of the sensor package are collectively influenced by the generated leakage flux of an existing flaw. An independent claim is included for an arrangement with a leakage flux probe and a magnetization unit, with which the body to be tested for the leakage flux testing is magnetized with a magnetic field.
