SENSOR SYSTEM
First Claim
1. A sensor array for evaluating the signals of a magnetically sensitive sensor element (22), with which the magnetic field changes caused by a transmitting element (10) are evaluated by calculating the difference, the transmitting element (10) including a large number of magnetic poles (14, 16),whereinat least one soft magnetic collector element (18, 20) is provided that taps the magnetic field of at least two identical magnetic poles (14, 16) of the transmitting element (10) and supplies it to the sensor element (22), the transmitting element (10) and the collector element (18, 20) being positioned such that they are movable relative to each other.

Abstract
Disclosed is a sensor array for evaluating the signals of a magnetically sensitive sensor, in which the changes in the magnetic field caused by a moved transmitting element (10) are evaluated by forming the difference. The transmitting element (10) is fitted with a plurality of magnetic poles (14, 16). A soft magnetic collecting element (18, 20) is provided which taps the magnetic field of at least two magnetic poles (14, 16) of the same kind and feeds said magnetic field to the sensor element (22).
