Zusammenfassung:	Two permanent magnets at an adjustably fixed distance from each other face each other with like poles and are mounted on the moveable portion of a pressure-sensitive membrane, with one magnet near the membrane, and the other one at some distance away, while a Hall-effect sensor of fixed position is located between the magnets. The null point of the output scale and the scope of the transducer characteristic can be set either by adjusting the position of the magnets or by adjusting the amount of their magnetization.
