Abstract
According to the invention there is provided a pulse signal generator comprising a plurality of magnetic elements arranged in an imaginable plane and capable of producing large Barkhausen jumps; a first unit for generating a magnetic field, which is changed by the object to be detected to cause the magnetic elements to produce the large Barkhausen jumps, the first unit consisting of a pair of magnet/yoke combinations provided on opposite sides of said imaginable plane such that their poles are oriented in opposite directions, forming a detecting area at an end thereof; a second unit for detecting the large Barkhausen jumps to produce corresponding pulse signals; and first and second adjusting yokes being movable on one of the magnet/yoke combinations along one of the magnetic elements and on the other of the magnet/yoke combinations along the other of said magnetic elements, respectively.
