GRADIENT OF MAGNETIC FIELD STRENGTH Russian patent published in 2020 - IPC G01B7/00 

FIELD: monitoring and measuring equipment.

SUBSTANCE: invention relates to instrumentation and can be used for measurement of gradient of magnetic induction or intensity. Gradiometer of magnetic field intensity comprises two parallel oriented semiconductor rod elements excited by this field, having two current end contacts each and side potential electrodes, as well as an indicator, wherein end contacts of semiconductor elements are connected to the output of the generator of linearly increasing voltage, and potential electrodes located on their side surfaces are connected to inputs of the controller, and the output of the latter is connected to the control input of said generator.

EFFECT: high sensitivity of a gradiometer of magnetic field intensity and improved processability thereof.
