Embodiment Construction

[0017] The present invention will be described in detail below with reference to the embodiments in the drawings:

[0018] Figure 1 to Figure 5 It is a fixed pendulum magnetic induction angular displacement sensor of the present invention, especially an axial magnetic field induction magnetic induction angular displacement sensor. It consists of a magnetic induction sensor 1, a permanent magnet 2, bearings 3, 4, a supporting connector 5, a rotating shaft 6, and a fixed The brackets 8, 9 and the base 10 are composed; the magnetic induction sensor 1 is fixed on the bracket 9, and the brackets 8, 9 are mounted on the bottom seat 10; the permanent magnet 2 is a cylindrical shape, the thickness is basically the same, the material density is basically uniform, and there is at least one axis A cylindrical permanent magnet with a sloped end. The north and south poles of the permanent magnet are at the ends of the cylinder. The permanent magnet 2 is installed coaxially with the rotating s...

Abstract

The magnetic induction angular shift sensor for detecting rotating, inclined and vertical angular shift consists of permanent magnet, and magnetic induction sensor fixed to the frame. The permanent magnet has one axial end plane inclined to the rotating shaft and produces magnetic field, and with the coaxial rotation of the magnetic induction sensor relative to the permanent magnet, the distance between the axial end plane and the magnetic induction sensor changes gradually and the sensing area of the magnetic induction sensor senses gradually changed magnetic field representing the detected angular shift. The present invention has higher sensitivity when the rotating shaft, permanent magnet, etc. is regulated.

Description

Technical field [0001] The invention relates to a fixed pendulum magnetic induction rotation, tilt, and perpendicularity angular displacement sensor, but it is not limited to this. Background technique [0002] The Chinese invention patent ZL Patent No. 89102296.1 discloses an angular displacement sensor that detects rotation, tilt, and perpendicularity, called a "capacitive angular displacement sensor". Its disadvantage is: due to the structure of this type of angular displacement sensor Complexity, large volume, high manufacturing precision requirements, and difficult to manufacture, such as high requirements for parallelism between the fixed electrode plates, high requirements for the flatness of the moving electrode plate surface, and other shortcomings that are not conducive to mass production. Summary of the invention [0003] The purpose of the present invention is to overcome the above-mentioned shortcomings of the prior art, and provide a tilt angle displacement sensor ...
