GEAR MEASURING INDUCTANCE Russian patent published in 1999 - IPC

FIELD: inductance measurement. SUBSTANCE: gear has source of constant voltage, measured inductance coil, standard inductance coil, meter in which capacity meter of passed electric discharge is used, two keys, two diodes. Source of constant voltage and one of keys form electric circuit parallel to which two electric networks are connected. One of them includes meter of passed electric discharge and one of diodes, the other one incorporates standard inductance coil, the other key and the other diode. Measured inductance coil is connected to leads of section of the latter. Anodes of diodes are linked to negative pole of source of constant voltage . EFFECT: increased productivity and reliability of gear. 1 dwg
