Pickups are arranged with butts facing one another along one axis, are electrically insulated one from another and are interjoined with fixing members. Each pickup is produced in the form of two coaxial electrodes. Adjacent pickups are installed with clearance that is defined by formula Z=0.01 K((γ₁-γ₂))L. Butts of electrodes of each pickup are located in one plane perpendicular to axis of pickups in clearance between them. System is fitted with screens mounted on butts of pickups over entire area of butts and are electrically insulated from pickups.
