DEVICE MEASURING MAGNETIC FIELDS Russian patent published in 1998 - IPC

FIELD: instruments measuring components and total vector of induction of field of the Earth. SUBSTANCE: device measuring magnetic fields has digital computation unit 1, current stabilizer 2, commutator 3, ferrosonde comparator 4 with ferrosonde transmitter, digital integrator 5 and code-to direct current converter 6. Insertion of flip-flop 7, of delay element 8 and formation of new functional couplings make it possible to carry out completely autonomous formation of test signal adopted to measured field. Only one bus of remote transmission of signal CONDITION is needed to control former of test signal. EFFECT: enhanced authenticity of measurements. 2 dwg
