Inductive angle measurement sensor, e.g. for measuring the torsion angle of a steering column, has inductively coupled rotors mounted at a distance from each other on a torsion bar

摘要

#CMT# #/CMT# Inductive angle measurement sensor comprises: a stator (1) with at least an excitation element (4) and at least a first receiver element (4); a first rotor (2); a second rotor (3) that has at least an inductive coupling element (10) and; a torsion element (9) on which the rotors are arranged at a distance from each other. #CMT#USE : #/CMT# Inductive angle measurement sensor, e.g. for measuring the torsion angle of a steering column. #CMT#ADVANTAGE : #/CMT# The design of the inventive sensor permits rotation of the torsion element. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows a perspective view of an inventive sensor arrangement. 1 : stator 4 : excitation coil 8 : ASIC, application specific integrated circuit, for signal processing and evaluation 5, 6 : coils 7 : ASIC 2, 3 : rotors 10 : inductive coupling element 9 : torsion rod.
