Abstract
Изобретение относитс к измерительной технике и предназначено дл измерени плотности зар да на поверхности различных зар женных объектов. Цель изобретени - упрощение при одновременном повышении чувствительности датчика. Благодар выполнению механического резонатора датчика в виде закрепленной по периметру круглой плоской трехслойной мембраны, образованной жестко соединенными по всей площади через диэлектрическую прокладку измерительным электродом и магнитным корем, достигнуто упрощение конструкции датчика. При этом вследствие улучшенной экранировки измерительного электрода от обмотки 2 электромагнита близко расположенным соединенным с общей шиной магнитным корем повышена чувствительность датчика. Датчик содержит также корпус 1, неподвижный сердечник 3 электромагнита, регулировочное кольцо 7.3 ил.The invention relates to a measurement technique and is intended to measure the density of a charge on the surface of various charged objects. The purpose of the invention is to simplify while increasing the sensitivity of the sensor. Due to the implementation of the mechanical resonator of the sensor in the form of a circular flat three-layer membrane fixed around the perimeter, which are rigidly connected over the entire area through a dielectric gasket with a measuring electrode and a magnetic crust, a simplified sensor design has been achieved. At the same time, due to the improved shielding of the measuring electrode from the winding 2 of the electromagnet by a closely located magnetic core connected to a common busbar, the sensitivity of the sensor is increased. The sensor also includes a housing 1, a fixed core 3 of the electromagnet, an adjusting ring 7.3 Il.
