Description

Дл  измерени  емкости конденсаторов примен ют способы, основанные на сравнении измер емой емкости с эталонным конденсатором .Methods based on comparing the measured capacitance with a reference capacitor are used to measure the capacitance of capacitors.

Предлагаемый способ более совершенен , так как повышает точность и расшир ет пределы измерени .The proposed method is more perfect as it increases the accuracy and extends the limits of measurement.

Это достигаетс  тем, что измер емый конденсатор включают на вход усилител  посто нного тока с глубокой отрицательной обратной св зью, в цепь которой включен эталлонный конденсатор, и определ ют искомую емкость по величине напр жени  на выходе указанного усилител .This is achieved by including the measured capacitor at the input of a direct current amplifier with deep negative feedback, the circuit of which includes the reference capacitor, and determining the desired capacitance by the magnitude of the voltage at the output of the specified amplifier.

На чертеже изображена принципиальна  схема измерени  емкости конденсатора по предлагаемому способу.The drawing shows a schematic diagram of measuring the capacitance of a capacitor according to the proposed method.

Провер емый конденсатор 1 включают на вход усилители 2 посто нного тока, содержашего эталонный конденсатор 3 в цепи глубокой отрицательной обратной св зи .The tested capacitor 1 is connected to the input of the amplifiers 2 of direct current, which contains the reference capacitor 3 in the deep negative feedback circuit.

Если емкость конденсатора 3 из:вестна , то коэффициент передачиIf the capacitance of the capacitor is 3 out of: is known, then the transfer coefficient

усилител  будет зависеть исключительно от емкости конденсатора 1. При подаче на вход такого усилител  напр жени  определенной величины на выходе усилител  по витс  напр жение пропорциональное его коэффициенту передачи. Следовательно , измер   вольтметром 4 выходное напр жение усилител , можно судить о величине емкости конденсатора 1. Переключатель служит дл  подключени  вольтметра 4 на калибровку и на отсчет.the amplifier will depend solely on the capacitance of the capacitor 1. When a voltage amplifier is applied to the input of a certain size, the output voltage of the amplifier is proportional to its gain. Therefore, by measuring with the voltmeter 4 the output voltage of the amplifier, it is possible to judge the capacitance capacitance value 1. The switch serves to connect the voltmeter 4 for calibration and for counting.

Предмет изобретени Subject invention

Способ измерени  емкости конденсатора путем сравнени  ее с емкостью эталонного конденсатора, отличаюш,ийс  тем, что, с целью повышени  точности и расширени  пределов измерени , измер емый конденсатор включают на вход усилител  посто нного тока с глубокой отрицательной обратной св зью, в цепь которой включен эталонный конденсатор, и определ ют искомую емкость по величине напр жени  на выходе указанного усилител .The method of measuring the capacitor capacitance by comparing it with the capacitance of the reference capacitor is distinguished by the fact that, in order to increase the accuracy and extend the measurement limits, the measured capacitor is connected to the input of a direct current amplifier with deep negative feedback, in which the reference circuit is connected. capacitor, and determine the desired capacitance by the magnitude of the voltage at the output of the specified amplifier.
