Abstract:
A leakage flux probe for non-destructive leakage flux-testing of magnetizable bodies comprising a plurality of coils for detection of near-surface flaws in the body, wherein the coils have a degree of sensitivity which is dependent upon the orientation of the flaws in the body, and wherein coils having a different degree of sensitivity are disposed in the leakage flux probe with a first type of coil having a high degree of sensitivity for longitudinal flaws or transverse flaws and a second type of coil having a high degree of sensitivity for oblique flaws.
