PASSIVE MARKER

摘要

FIELD: search systems.;SUBSTANCE: invention relates to the field of search systems for determining the location of underground communications. The effect in the claimed solution is achieved by applying the principle of rolling friction, which is significantly less than sliding friction, for this, a body with a spherical cavity is provided in the passive marker, inside which an LC circuit tuned to the required resonant frequency is placed, installed inside a spherical holder with an offset to the axis the winding of the LC-loop by the center of gravity, while the holder is installed with the possibility of rotation inside the housing due to balls evenly distributed over its surface, held by the separator.;EFFECT: reducing the friction of the outer surface of the LC-contour holder relative to the inner surface of the marker body.;1 cl, 1 dwg
