UA81794U - Differential inductive sensor - Google Patents

Abstract

A differential inductive sensor includes first and the second pairs of magnetic conductors with coils placed in zones of opposite ends of the cross armature at axles displaced from the ends of the cross armature by distance equal to half of radius of magnetic conductor with coil, at that the magnetic conductors with coils are connected to amplification-transformation channels, and the magnetic conductors with coils placed on same axles through amplification-transformation channels are connected to the input of the adder through the adder. The third and fourth pairs of magnetic conductors with coils placed in normal to each other planes with main pairs of magnetic conductors with coils symmetrically with respect to the cross armature at opposite side on axles displaced from the ends of the cross armature by distance equal to half of radius of magnetic conductor with coil. The additional magnetic conductors with coils placed on same axles through amplification-transformation channels are connected to additional inputs of the adder through the adder, and the cross armature is arranged in +-like form. Two additional cross armatures in +-like form are used, those are placed symmetrically at both sides outside the magnetic conductors with coils and fixed with a link to the main cross armature in +-like form.
