Description
(5 ft) УСТРОЙСТВО ДЛЯ ИЗМЕРЕНИЯ ДИЭЛЕКТРИЧЕСКИХ СВОЙСТВ ВЕЩЕСТВ(5 ft) DEVICE FOR MEASURING THE DIELECTRIC PROPERTIES OF SUBSTANCES
Изобретение относитс к измерительной технике и может быть исполь .зовано дл сравнени диэлектрических свойств веществ, в частности дл . вы влени различий между контрольными и опытным;; биологическими объектами.The invention relates to a measurement technique and can be used to compare the dielectric properties of substances, in particular for. you make a difference between the control and experienced ;; biological objects.
Известие. устройство, содержащее . генератор качак цейс частоты, подключенный к входу нелинейного смесител , выход которого подключен к индикатору . К входу одного из генераторов подключена конденсаторна чейка с исследуемым образцом. Изменение емкости чейки с образцом приводит к по влению биений на выходе смесител , по которым и измер етс емкость чейки 13,News. device containing Kachak generator of frequency, connected to the input of a non-linear mixer, the output of which is connected to the indicator. A capacitor cell with a test sample is connected to the input of one of the generators. A change in the capacitance of the cell with the sample leads to the appearance of beats at the exit of the mixer, from which the capacity of the cell 13 is measured,
Наиболее близким к изобретению вл етс измерительное устройство, содержащее генератор кача1 1ейс частоты , подключеннЕлй к .измерительному мосту, в одно из плеч которого включена измерительна чейка с исследуемым образцом. Индикаци сдвига фаз осуществл етс широкополосным фазометром С2.The closest to the invention is a measuring device containing a frequency generator, 1ays frequency, connected to a measuring bridge, in one of the arms of which a measuring cell with a test sample is included. The phase shift is indicated by a C2 wideband phase meter.
Недостатком известного устройства - вл етс отсутствие визуального панорамнога контрол разности диэлектрических свойств исследуемых объектов в широкой области частот.A disadvantage of the known device is the lack of a visual panoramic control of the difference in dielectric properties of the objects under study in a wide frequency range.
Цель изобретени - повышение достоверности измерени в широком диапазоне частот путем визуального панорамного контрол разности диэлектрических свойств исследуемых объектов.The purpose of the invention is to increase the reliability of measurements in a wide frequency range by visual panoramic monitoring of the difference in dielectric properties of the objects under study.
Поставленна цель достигаетс тем, The goal is achieved by
10 что в устройство дл измерени диэлектрических свойств веществ, содержащее генератор качающейс частоты, подключенный к измерительному мосту , в одно из плеч которого включена 10 that in a device for measuring the dielectric properties of substances, containing a oscillating frequency generator, connected to a measuring bridge, in one of whose arms it is included
15 измерительна чейка, а.диагональ подключена к индикатору, введена дополнительна измерительна чейка, включенна. в другое плечо моста, а диагональ моста подключена к индика20 тору через детекторы и усилитель разности .15 measuring cell, a. Diagonal connected to indicator, additional measuring cell entered, included. to the other shoulder of the bridge, and the bridge diagonal is connected to the indicator through the detectors and the difference amplifier.
Кроме того, в качестве индикатора используют измеритель амплитудно-частотных характеристик.In addition, as an indicator using the meter amplitude-frequency characteristics.
