Device for contactless measurement on rotating shafts three independent displacement coordinates and three angles of rotation independent

摘要

The present invention relates to a device for measuring position, rotation and pitch and yaw of a rotary shaft (1) characterized by having at least one permanent magnet (2) with magnetization in a diametrical direction fixedly connected to said rotary shaft ( 1) and by having in addition to a first set of at least four sensors uniaxial magnetic field (3), (4), (5) and (6) and a second set of at least two sensors (7) and (9) , each of said sensors (3), (4), (5), (6), (7) and (9) fixed and separate each at a distance of at least one permanent magnet (2), their sensitive axes oriented radially and the first set further characterized by sensors arranged in pairs in two radial axes, further characterized by the two sets being displaced axially fixed distance from each other.
