Abstract

Использование: в электроизмерительной технике. Сущность изобретени : преобразователь содержит генератор 1, трансформатор 2, опорную Со 3 и измер емую Сх 5 емкости датчика, два ключа 4.9, емкость С 6. усилитель 7, выпр митель 8, логометр 10, мультивибратор 11. Погрешность от делени  двух напр жений , одно из которых пропорционально Со, а второе - разности между опорной и измер емой емкост ми датчика будет существенно меньше. 1 ил.Usage: in electrical engineering. SUMMARY OF THE INVENTION: the converter comprises a generator 1, a transformer 2, a reference Co 3 and a sensor capacitance Cx 5 measured, two keys 4.9, a capacitor C 6. an amplifier 7, a rectifier 8, a logometer 10, a multivibrator 11. Error from the division of two voltages, one of which is proportional to Co, and the second - the difference between the reference and measured capacitances of the sensor will be significantly smaller. 1 ill.
