EDDY-CURRENT DISPLACEMENT TRANSDUCER Russian patent published in 2003 - IPC

FIELD: measuring equipment, applicable for checking of linear displacements of rotor machines in power engineering, petrogas industry and other branches. SUBSTANCE: transducer sensing element has two measuring windings having the shape of right-angles triangles, being in contact with the hypothenuses, and an exciting winding. The areas of the measuring windings make up a rectangle equal to the rectangle of the exciting winding. The windings are made by the printing method of several layers of helical coils on dielectric backings. The layers of helical coils are assembled in a rectangular foliated pellet. The layers of coils of the exciting winding alternate with the layers of coils of the measuring windings. The measuring windings are connected differentially. The transducer is installed on the frame of the rotor machine in the center of the measuring shoulder of the rotor machine. EFFECT: linearly of the transducer static characteristic and provided its adaptation to the measuring shoulders of different width. 5 dwg
