Description
но соединенные reHepiarop переменного напр жени высокой частоты, измерительную цепь с датчиком и эталонным резистором, усилитель сигнала измерительной цепи, выпр митель и показывающий прибор, датчик выполнен с полусферическим металлическим электродом, соединенным через эталонный резистор с генератором переменного напр жени высокой частоты.but connected by reHepiarop high frequency ac voltage, measuring circuit with sensor and reference resistor, measuring circuit signal amplifier, rectifier and indicating device, the sensor is made with a hemispherical metal electrode connected through a reference resistor to a high frequency alternator.
На чертеже представлена схема предлагаемого устройства.The drawing shows a diagram of the proposed device.
Устойство содержит генератор 1 переменного напр жени высокой частоты ,измерительную цепь 2 с Датчиком 3 и эталонным резистором k, усилиfeль 5 сигнала измерительной цепи, выпр митель 6 и показывающий при .бор 7.The device comprises a high frequency alternating voltage generator 1, a measuring circuit 2 with a sensor 3 and a reference resistor k, an amplitude 5 of the measuring circuit signal, a rectifier 6, and showing at set 7.
Полусферическа форма мтелли ческого электрода 8 датчика 3 способствует минимальному осаждению примесей, содержащихс в многокомпонентной жидкой среде на его поверхности , и равномерному распределению тока, а частота и плотность тока высокой частоты вырабатываемого генератором 1, выбрана такой, что исключаетс вли ние влени пол ризации электрода на показани прибора. Падение переменного напр жени высокой частоты на эталонном резисторе 4, пропорциональное электрической проводимости многокомпонентной жидкой среде, усиливаетс усилителемThe hemispherical shape of the cell electrode 8 of sensor 3 contributes to the minimal deposition of impurities contained in the multicomponent liquid medium on its surface and uniform current distribution, and the frequency and current density of the high frequency produced by the generator 1 is chosen such that the effect of the polarization phenomenon on the electrode on the instrument readings. A drop in high frequency ac voltage across a reference resistor 4, proportional to the electrical conductivity of a multi-component liquid medium, is amplified by an amplifier
5, выпр мл етс выпр мителем 6 и измер етс показывающим прибором 7Предлагаемое устройство позвол ет повысить точность измерений на 1015 за счет уменьшени вли ни на показани примесей, содержащихс в жидкой среде.5, is rectified by a rectifier 6 and measured by the indicating device 7 The proposed device allows to increase the measurement accuracy by 1015 by reducing the influence on the readings of impurities contained in the liquid medium.
