FIELD: measurement equipment.
SUBSTANCE: converter comprises an active measurement circuit on an amplifier with capacitance feedback and a sensor in an input circuit, a comparator of voltages and a scaling converter for additive correction of initial capacitance, units of sampling and storage, a logometric converter. Besides, the converter comprises a differentiator with alternating parameters, a gate multivibrator, a delay element, additional units of sampling and storage, logometric converters.
EFFECT: increased accuracy and efficiency.
