DEVICE FOR MEASURING ELECTRIC CAPACITY Russian patent published in 2007 - IPC G01R27/00 

Abstract RU 2308727 C1

FIELD: measuring equipment, possible use in various technological areas for measuring electrical capacity.

SUBSTANCE: device for measuring electric capacity contains two monostable multivibrators, coupled in accordance to circle active oscillator circuit, measured and standard capacitors, coupled in time-setting RC-circuits of monostable multivibrators, indication block with integrating unit at its input, adder, support voltage supply and two reversible keys, control input of each of which is connected to output of corresponding monostable multivibrator, and outputs - to inputs of integrating unit, first inputs of reversible keys are connected to zero potential bus, and second outputs are connected to output of adder, first input of which is connected to output of indication block, and second input is connected to output of support voltage source.

EFFECT: increased precision and linearity of static characteristic of device for measuring electric capacity.
