| 摘要 |
The invention relates to security devices, particularly devices for detecting the unauthorized access to devices accounting the consumption of energy resources, for example electric energy, gas, water, by the action of a magnetic field.The magnetic field indicator, according to the invention, includes a non-magnetic body, formed of at least two sections, at least one of which is made transparent, the body being made with the possibility of hermetic fixation on an outer surface, and a magnetically sensitive element containing a viscous mixture of magnetic particles on base of binder additives, applied on the inner surface of the body in arbitrary form and made with the possibility of changing the form under the action of a magnetic field. |
