Abstract
The object of the invention is a device with two Hall generators (12, 14) for measuring the gradients of magnetic leakage fields in the non-destructive testing of materials. The two Hall generators (12, 14) are arranged at a distance from each other with their broad sides on a flat carrier substrate (18). They are positioned along a common line (36) with respect to which they each have the same alignment. Furthermore the two Hall generators are arranged close to the edges (40) of two opposite sides of the carrier substrate (18) that are free of connections.
