Abstract

Изобретение относится к охранным устройствам, в частности к устройствам выявления несанкционированного доступа к приборам учета потребления энергетических ресурсов, например электроэнергии, газа, воды, и другим контрольным приборам, путем воздействия магнитным полем. Индикатор представляет собой устройство, имеющее корпус, образованный выпуклым полым прозрачным участком и отходящим от него по периметру основания боковым участком, причем боковой участок выполнен с возможностью герметичной фиксации на сопрягающейся с ним внешней поверхности. Индикатор снабжен магниточувствительным узлом, выполненным в виде магниточувствительного элемента, содержащего вязкую смесь магнитных частиц на основе связующих присадок. Магниточувствительный элемент нанесен на внутреннюю поверхность выпуклого участка корпуса в форме пятна произвольной конфигурации, которая меняется под воздействием магнитного поля. Результат, достигаемый с помощью данного изобретения, состоит в упрощении конструкции индикатора магнитного поля и повышении степени достоверности выявления наличия магнитного поля при несанкционированном воздействии на приборы учета потребления энергетических ресурсов.The invention relates to security devices, in particular to devices for detecting unauthorized access to metering devices for the consumption of energy resources, such as electricity, gas, water, and other control devices, by exposure to a magnetic field. The indicator is a device having a body formed by a convex hollow transparent section and a side section extending from it along the base perimeter, the side section being configured to be hermetically fixed on the external surface that mates with it. The indicator is equipped with a magnetically sensitive unit made in the form of a magnetically sensitive element containing a viscous mixture of magnetic particles based on binders. The magnetically sensitive element is applied on the inner surface of the convex part of the body in the form of a spot of arbitrary configuration, which varies under the influence of a magnetic field. The result achieved using this invention is to simplify the design of the magnetic field indicator and increase the degree of reliability of detecting the presence of a magnetic field when unauthorized exposure to metering devices for the consumption of energy resources.
