INVARIANT MEASURING BRIDGE

摘要

FIELD: instruments, in particular, design of reactance converters which are invariant with respect to external influence. SUBSTANCE: device has four resistive converters, one of which has alternating parameters, operational amplifier, power supply of measuring bridge, differential amplifier, voltage repeater or scaling amplifier and dividing unit, which inputs are connected to outputs of voltage repeater and differential amplifier. EFFECT: increased precision. 1 dwg
