Abstract |
AB |
[DE] Die Erfindung betrifft eine Messvorrichtung (1) zur berührungslosen Erfassung eines ferromagnetischen Gegenstandes (4, 5). Die Messvorrichtung umfasst ein Hall-Element (3) und mindestens einen Permanentmagneten (2), wobei zwischen dem Hall-Element und dem Permanentmagneten ein Luftspalt (6) angeordnet ist. Weiter weist der Permanentmagnet (2) an mindestens einer seiner Stirnseiten ein weichmagnetisches Bauteil (7) auf, welches zwischen dem Permanentmagneten (2) und dem Hall-Element (3) angeordnet ist.
[EN] The invention relates to a measuring device (1) for contactlessly detecting a ferromagnetic object (4, 5). The measuring device comprises a Hall element (3) and at least one permanent magnet (2), an air gap (6) being located between said Hall element and said permanent magnet. The permanent magnet (2) also has a soft magnetic component (7) on at least one of its front sides, said component being located between the permanent magnet (2) and the Hall element (3). |
