MAGNETO-MODULATED INDUCTION PICKUP OF LINEAR MOVEMENT Russian patent published in 1994 - IPC

FIELD: measurement technology. SUBSTANCE: this pickup includes U-shaped magnetic circuit, three or four A.C. windings located on it meant for connection into bridge circuit of A.C. measurement as well as two or four magnetization D.C. windings mounted for linear movement along parallel sections of magnetic circuit and designed for connection with proper test object. Inductance of proper A.C. winding changes depending on position of each of magnetization windings which leads to unbalance of bridge measurement circuit. EFFECT: expanded functional capabilities of magneto-modulated induction pickup of linear movement. 2 cl, 4 dwg
