CAPACITIVE ABSOLUTE ANGULAR DISPLACEMENT TRANSDUCER Russian patent published in 2022 - IPC G01B7/30 

FIELD: measuring equipment.

SUBSTANCE: invention relates to measuring equipment and can be used for highly accurate absolute measurements of angular displacements. In the capacitive absolute angular displacement transducer, the receiving liners of precise and rough reading scales of the transducer are made identical and consist of the same integer number of segmented liners in each of the four sectors of the annular stator plate, wherein each four segmented receiving liners located one after the other form an equal integer number of reading nodes in each sector of the transducer, and located on two sides of the rotor plate are mirror-symmetrical pairwise electrically connected conductive liners of the precise and rough reading scale, the precise reading scale whereof comprises one pair of liners made in the form of radially symmetrical platforms, the rough reading scale of the rotor comprises one or two pairs of liners made in the form of radially symmetrical platforms.

EFFECT: increase in the measurement accuracy and improvement in the noise protection in condition of influence of electromagnetic interference.
