FIELD: measurement technology. SUBSTANCE: method can find use in technology and scientific research in the interests of nuclear and heat power industry for measurement of electric and nonelectric quantities in media with high-varying and nonuniform temperature fields. Method of compensation for temperature error of inductive primary converter sums up A C voltage and D C voltage, sum of voltages is used to feed inductive primary converter, alternating voltage output by inductive primary converter is filtered, is rectified by converters of rectified mean value, is filtered, summed up and amplified. Taking this signal as working D C voltage output by inductive primary converter is filtered, one voltage is subtracted from another, is amplified and considered as correcting signal. This correcting signal is subtracted from working signal, this difference is multiplied by correcting signal and recorded. EFFECT: increased measurement accuracy. 3 dwg
