DIGITAL FERROPROBE MAGNETOMETRE Russian patent published in 2011 - IPC G01R33/02 

FIELD: physics.

SUBSTANCE: digital ferroprobe magnetometre, having three ferroprobes, the outputs of which are connected to inputs of three selective amplifiers respectively, the outputs of which are connected to first inputs of three storage-sampling devices, the first outputs of which are connected to first inputs of three analogue-to-digital converters, the second inputs of which are connected to third outputs of a logic unit, the output of which is connected to the output of a master generator, and the second output is connected to second inputs of the storage-sampling devices, the second outputs of which are connected to second inputs of the ferroprobes, wherein the digital ferroprobe includes a parametric voltage generator, the input of which is connected to the first output of the logic unit, and the output is connected to the first inputs of the ferroprobes.

EFFECT: higher accuracy and stability of measurement.
