| 摘要 |
Displacement sensor arrangement comprising at least one primary coil (1), at least a first and a second secondary coil (3, 4) and at least one magnetically soft coupling element (2), which magnetically couples the primary coil (1) and the two secondary coils (3, 4), the displacement sensor being designed so that a position and/or deflection depending on the magnetic coupling between the primary coil (1) and at least the first and second secondary coil (3, 4) is detected, the displacement sensor arrangement having a signal processing unit (5), which is designed to perform digital signal processing of at least one electrical variable of the two secondary coils (3, 4) and determine the position and/or deflection, the signal processing unit (5) having at least one Goertzel filter (6). |
