Description
датчик / - диод 4 - конденсатор 7 - обща шина генератора 3. Зар дный ток датчика / зар жает конденсатор 7, который разр жаетс через миллиамперметр 5, что вызывает отключение стрелки последнего.sensor / - diode 4 - capacitor 7 - common generator bus 3. Sensor charging current / charges capacitor 7, which is discharged through milliammeter 5, which causes the arrow of the latter to turn off.
При другом полупериоде тока генератора 3 датчик / перезар жаетс ио цеии: сигнальный выход генератора 3 - датчик 1 - диод 5 - обща щина генератора 3. цикл иовтор етс .In the other half-period of the generator 3 current, the sensor / recharges itself is the following: generator signal output 3 - sensor 1 - diode 5 - generator 3 total. The cycle is repeated.
Поскольку емкости датчиков I 2 завис т от уровней рабочей жидкости /Zj и h соответственно , то и перезар дные токи будут измен тьс .Since the capacitances of the sensors I 2 depend on the working fluid levels / Zj and h, respectively, the overcharge currents will vary.
Так какBecause

где / - ток, протекающий через нагрузку (в данном случае через катущку миллиамперметра); С - емкость датчика; и - размах напр жени иере.менногоwhere / is the current flowing through the load (in this case, through a milliammeter meter); C - sensor capacity; and - the magnitude of the tension
тока {на выходе генератора 5); / - частота переменного тока, и учитыва , чтоcurrent {at the output of the generator 5); / is the frequency of the alternating current, and taking into account that

/ /(/1).Стрелки миллиамперметров 6 отклон ютс пропорционально токам / и /2, протекающим через их «атущки, т. е. проторциоНально уровн м жидкости в сосудах . Показани миллиамлерметров считывают и вычисл ют разность показаний./ / (/ 1). The arrows of milliammeters 6 deflect in proportion to the currents / and / 2 flowing through their source, i.e., it is protracted to the levels of liquid in the vessels. Milliammeter readings are read and the difference in readings is calculated.
котора характеризует величину исходного презышсии . В схеме может быть icпользован и один миллиамперметр, поочередно подключаел1ый посредством переключател к той или иной цепи.which characterizes the value of the original prezyshsii. In the circuit, one milliammeter can also be used, alternately connected via a switch to a particular circuit.
