A TWO-CHANNEL TRANSDUCER FOR CAPACITIVE SENSORS

摘要

A procedure for the experimental investigation of an active transducer of the parameters of electrical circuits, based on a two-channel amplifier with additive correction is described, and results are presented. The possibility of reducing the errors of converting capacitance into voltage to 0.2% in the 10-50 kHz range for a cable capacitance of up to 1000 pF is confirmed.
