Abstract

Использование: в измерительной технике дл  измерени  параметров материалов. Сущность изобретени : преобразователь содержит емкостный датчик 1, два операционных усилител  2 и 3. высокочастотный генератор, построенный на однопереход- ном транзисторе 4, двух резисторах 5 и 6, конденсаторе 7, трансформатор 9 с обмотг камиЗ, 10,13, симистор 11, диод 12. Выполнение генератора высокочастотным, в также введение трансформатора 9, диода 12, симистора 11 позволило упростить преобразователь и повысить точность. 1 ил.Usage: in measuring technique for measuring material parameters. Summary of the invention: the converter contains a capacitive sensor 1, two operational amplifiers 2 and 3. a high-frequency generator built on a single-junction transistor 4, two resistors 5 and 6, a capacitor 7, a transformer 9 with KAMZ winding, 10.13, a triac 11, a diode 12. The implementation of the high-frequency generator, as well as the introduction of a transformer 9, a diode 12, a triac 11 made it possible to simplify the converter and improve accuracy. 1 ill.
