Detector of mobile, or movable part, electrically and/or magnetically conductive, incorporates two electric circuits and control and/or regulating device, with specified components of both electric circuits

摘要

Detector comprises first electric circuit containing first inductive element (9) and first voltage source (11), and second electric circuit with magnetic field sensitive element (1) and impedance, capacitive element (2) and second inductive element (3). Control and/or regulating device (5), after second circuit energizes load (8). Both electric circuits are mutually separated. Preferably, first electric circuit provides excitation for magnetic field generation. Typically, second electric circuit detects magnetic field, with magnetic field sensitive element as magneto-resistor, or magneto-impedance.
