CONVERTER OF CAPACITANCE VALUE TO TIME INTERVAL Russian patent published in 2000 - IPC

Abstract RU 2153176 C1

FIELD: instruments. SUBSTANCE: direct voltage source is connected through first gate to measuring dipole, which is designed as serial circuit of inductance coil and by-pass resistor, which is connected in parallel to capacitor to be measured. In addition, measuring dipole is connected through second gate to integrator, low-pass filter, differentiating unit, and control unit, which output is connected to control input of generator, which controls operations of gates and provides their alternating switching. Zero voltage at output of differentiating circuit corresponds to zero time interval. EFFECT: increased sensitivity. 1 dwg
