FORMER OF OUTPUT SIGNAL OF INDUCTIVE DIFFERENTIAL INSTRUMENT TRANSDUCER Russian patent published in 2004 - IPC

FIELD: measurement technology, measurement of electric and non-electric quantities during research in nuclear and thermal power engineering. SUBSTANCE: former of output signal of inductive differential instrument transducer incorporates AC source, inductive differential instrument transducer with two branches as minimum, two rectifiers and differential amplifier which outputs are connected to outputs of rectifiers coupled to outputs of branches of inductive differential instrument transducer. Capacitor is placed in addition between outputs of branches of inductive differential instrument transducer. Value of capacitance of this capacitor is selected experimentally such that multiplication error of transducer caused by ambient temperature is minimal. EFFECT: increased accuracy of measurements conducted with the aid of inductive differential instrument transducers operating in high-temperature environment thanks to reduction of multiplication error of these transducers. 1 cl, 1 dwg
