ACTUAL DISPLACEMENT TRANSFORMER-TYPE TRANSDUCER Russian patent published in 2001 - IPC

FIELD: measuring technology. SUBSTANCE: transducer has twin magnetic bridge. Each of four-arm bridges includes stationary magnetic core with diagonal jumper and moving magnetic core made as a ring with two diametrically-positioned poles. Rings are embraced by excitation winding loosely. Each of diagonal jumpers is provided with radial V-shaped slots made to definite depth. Measuring winding is positioned on solid part of diagonal jumpers. Electromotive force is caused in measuring winding during displacement of both measurement objects. Modulus of electromotive force is proportional to algebraic sum of angles of turn of these objects. Said transducer allows simultaneous measurement of angular displacement of other object. EFFECT: enlarged functional capabilities. 4 dwg
