COULOMBMETER SET Russian patent published in 1998 - IPC

FIELD: electrochemistry. SUBSTANCE: coulombmeter can be used in mechanical engineering to control process of deposition of electroplating in process of electrolysis and during operations related to charging and training of storage batteries and in other electric technologies. Object of present invention is provision of metered feed of definite quantity of electricity specified beforehand into electric load placed in DC circuit independent of current value of load current changing in time. Mix f set for coulombmetering analysis includes electrochemical cell connected to DC source, differential amplifier to which input precision resistor ( current pickup ) placed into circuit of electrochemical cell is connected, voltage-to-frequency converter ( pulse integrator of analog signal ) connected to output of differential amplifier and frequency divider placed between output of voltage-to-frequency converter and pulse counter. Set is supplemented with unit permitting passage of pulses, button key of start of set, unit setting dose of quantity of electricity in the form of button keys with unit of digital indication and controlled key of current commutation with control unit. EFFECT: provision of metered feed of definite quantity of electricity into electric load. 1 cl, 1 dwg
