FIELD: measuring technique.
SUBSTANCE: device comprises sources of excitation whose outputs are connected with the unmovable electrodes of corresponding channel. The capacitor is connected between the inverting input of the amplifier of each channel and conducting body. The frequencies of the voltages of the excitation sources differ at least by the double band of transmission of each of the channels.
EFFECT: simplified design.
