FIELD: measurement technology, radio and electrical engineering, automatics.
SUBSTANCE: instrument converter comprises two servo systems with two thermal converters and device summing alternating and direct currents, high- and low-frequency filters. Device summing alternating and direct currents is built on basis of operational amplifier, which is embraced by network of adjustable parallel negative voltage feedback. High- and low-frequency filters are intended to split spectrum of output signal of operational amplifier into variable and constant components. Thanks to employment of summing device based on operational amplifier that is embraced by network of adjustable negative feedback external factors and aging of resistors have no influence on equality of variable and constant components across output of operational amplifier.
EFFECT: enhanced precision of converter.
