ANGULAR DISPLACEMENT TRANSMITTER Russian patent published in 2003 - IPC

FIELD: measurement technology. SUBSTANCE: angular displacement transmitter includes base and body made as one unit in which stator with dielectric form of windings, rotor setting mobile screen in rotation and return cylindrical spring are installed. Form of windings is sectional: first part of it is formed by bushing with flange, second part is represented by bushing placed concentric on bushing of first part. Windings are dropped in circular slots made in side surfaces of bushings of first and second parts. Stator is equipped with immobile screen in the form of flat ring with two arc-shaped through cuts-out located at different distances from axis of turn of rotor. Ring is positioned perpendicular to axis of turn of rotor and is put on face surfaces of bushings of first and second parts of form of windings. Mobile screen is adjacent to immobile screen and has form of flat ring with two arc-shaped through cuts-out which shut off cuts-out of ring of immobile screen at least partially. Pairs of cuts-out of immobile screen and cuts-out of mobile screen are located equidistantly from axis of turn of rotor. Edges of each cutout are arranged in sector amounting to 110 degrees relative to axis of turn of rotor. Flat ring of mobile screen is placed on flat ring of immobile screen with spring loading with reference to transmitter base. EFFECT: simplified design and enhanced operational reliability of transmitter, reduced labor input to its manufacture. 13 cl, 3 dwg
