INDUCTIVE METER OF TRANSLATIONS Russian patent published in 1998 - IPC

FIELD: precision measurements. SUBSTANCE: invention allows both measurement circuits to be sustained under conditions of resonance controlling variable capacitance in each circuit in accord with law C-k L, where C is change of inductance of pickup, thanks to insertion of capacitor 15 or 16 with variable capacitance, capacitor 17 or 18 with constant capacitance, converter 13 or 14 used to control DC voltage of capacitor 15 or 16. EFFECT: enhanced sensitivity, expanded measurement range as compared with prototype. 1 dwg
