Изобретение относитс к измерительной технике и может быть использовано дл измерени малых токов в системах.автоматического регулировани .The invention relates to a measurement technique and can be used to measure small currents in automatic control systems.
Известен электрометрический усилитель , содержащий усилитель посто нного тока, измерительный резистор и корректирующие звень l. A electrometric amplifier is known that comprises a DC amplifier, a measuring resistor, and corrective links l.
Недостаток этого усилител заключаётсйч в том, что он позвол ет скомпенсировать в передаточной .функции устройства одну посто нную времени .The disadvantage of this amplifier lies in the fact that it allows one time constant to be compensated for in the transfer function of the device.
Наи5о.пее близок по техническому решен к предлагаемому электромеханический усилитель с регулируемой посто нной времени, содержащий усилитель постр нного тока, делитель напр жени , сумматор, корректирующие звень , измерительный резистор и входную цепь 2 у.The closest one is technically resolved to the proposed electromechanical amplifier with an adjustable constant time, containing a direct current amplifier, a voltage divider, an adder, corrective links, a measuring resistor, and an input circuit 2 y.
Недостаток данного устройства состоит в том, что дл создани компенсационных звеньев с нужной частотной характеристикой не9бходимо заранее определить величину импеданса измерительного резистора и входного импеданса усилител , что представл ет собой значительную сложность при настройке электрометра.The disadvantage of this device is that to create compensating links with the desired frequency response, it is necessary to determine in advance the magnitude of the impedance of the measuring resistor and the input impedance of the amplifier, which is a significant difficulty in setting up the electrometer.
Цель изобретени - упрощение настройки измерител .The purpose of the invention is to simplify the configuration of the meter.
