MAGNETOMETRIC TRANSDUCER Russian patent published in 2011 - IPC G01R33/02 

FIELD: physics.

SUBSTANCE: magnetometric transducer contains a magnetic conductor, two magnet antennae, a current generator; one has introduced into it a device for controlling difference of phases between current and voltage, a direct current cut-off filter, an alternating current cut-off filter; the magnet antennae are arranged at a distance from each other with opposite directional fields direction whereof is determined by magnetic axes of the corresponding magnet antennae while the magnetic conductor interacting with the said fields and placed between the magnet antennae so that it is conductively not connected to these magnet antennae and is designed in the form of a screen made of a magnetic material; each of the magnet antennae is designed in the form of a helical antenna connected to the corresponding vessel and forms with the latter a resonant circuit frequency resonance characteristics whereof correspond to operational frequency of the magnetometric transducer; magnetic axes of the said antennae are matched; each of the said resonant circuits is connected to the serially connected device for controlling difference of phases between current and voltage and the direct current cut-off filter; the current generator is represented by a direct current generator and connected to each magnet antenna via the alternating current cut-off filter so that output of the direct current cut-off filter is the output of the magnetometric transducer.

EFFECT: reduced self-noise level, capability of functioning in HF-UHF ranges and broad band of operational frequencies.
