DEVICE TO MEASURE DENSITY OF CURRENT IN LOCAL VOLUMES OF SOLID MEDIA Russian patent published in 2015 - IPC G01N27/00 

FIELD: measurement equipment.

SUBSTANCE: sensor of the device represents a thick-walled tube-dowel 1, made of a dielectric plastic material, on the outer cylindrical surface of which there are current electrodes 2 and 3, split by plastic dielectric gaskets 4 and on the reverse side. The tube-dowel with electrodes is inserted into a hole 6, previously drilled in the solid medium, and is spaced in it with a screw 10 screwed into it. Gaskets 4 and 5 are installed perpendicularly in a current line 8, flowing in the solid medium. A current recorder 9 is connected between current electrodes 2 and 3. A rotary lever-indicator 11 is fixed on the upper part of the dielectric tube perpendicular to the split of the tube-dowel.

EFFECT: increased accuracy of current density measurement in local volumes of solid media.
