CONTACTLESS PICKUP OF ANGULAR POSITION OF SHAFT Russian patent published in 2005 - IPC

FIELD: measuring engineering.

SUBSTANCE: contact pickup comprises base made of a sleeve provided with the through opening in the bottom, insert with the through opening made in the plane parallel to the plane of the base bottom, magnetic holder made of a rotation body, magnetic system, printed circuit board provided with a magnetoelectric converter, adapter connected to the printed circuit board, and lid. The plane of the insert having the opening separates the space of the lid that receives the printed circuit board from the space of the base through which the magnetic holder passes. One of the ends of the magnetic holder enters the opening in the base, and the other end that is used for connecting to the magnetic system is set in the opening of the insert for permitting rotation. The section of the magnetic holder arranged in the space of the base is provided with two collars, one of which abuts against the base bottom through the flexible member, and the other one abuts against the plane of the insert. The printed circuit board is mounted in the space of the lid for permitting the magnetoelectric converter mounted on it to be positioned in the zone of action of the magnetic system.

EFFECT: reduced labor consumption and cost of pickup production.
