Abstract

The invention relates to security devices, in particular to devices for identifying the unauthorized access to devices for accounting the consumption of energy resources, such as electricity, gas, water, by the influence of a magnetic field.Magnetic field indicator, according to the invention, includes a non-magnetic body, formed by a convex transparent hollow portion and a lateral portion deviating from it along the perimeter, made with the possibility of tight fixation to the outer surface, and a magnetosensitive element, containing a viscous mixture of magnetic particles on base of binding additives. The magnetosensitive element is deposited on the inner surface of the convex portion of the body in arbitrary shape and is made with the possibility of changing the shape under the influence of the magnetic field.The result of the invention is to simplify the design of the indicator and increase the accuracy of detecting the unauthorized influence by a magnetic field on the energy resources consumption accounting devices.
