MEASURING CONVERTER FOR CAPACITIVE PICKUP Russian patent published in 2003 - IPC

Abstract RU 2206887 C2

FIELD: humidity meters. SUBSTANCE: measuring converter incorporates master generator and push-pull amplifier stage with output transformer. Transformer matches amplifier with pickups of large capacitance. Consumption current of amplifier stage is output parameter of converter. Circuit stabilizing amplitude of voltage across transformer is intended to increase accuracy of conversion. EFFECT: expanded range of measured capacitances and provision for operation with averaging pickups of large dimensions or extent. 2 dwg
