COULOMETER AND METHOD OF COULOMETRY

摘要

FIELD: measurement of quantity of electricity. SUBSTANCE: current carrier flow is transformed into light quanta; electric charge is judged from number of light quanta. Charge measurement range may be widened due to introduction of light filter or set of light filters. Coulometer has current carrier transformer, light source brought into measuring circuit for which number of irradiated light quanta is proportional to number of current carriers, photoelectric converter and electric pulse counter. Light source is connected optically with photoelectric converter which has output connected to input of the counter. EFFECT: improved precision; improved reliability. 2 cl, 4 cl, 1 dwg
