Бездемонтажний контроль похибок вимірювального перетворення за випадковими сигналами вимірювальної інформації

Abstract

A statistical model for the residual variance of redundant transducers output signals which allows to control the progressive changes of systematic and random errors in the operating impacts of measured physical quantities without disconnecting the transducers for verification is discussed. The statistical modeling for linear measuring transformations of dynamic quantities results, which confirm the efficiency of the residual variance as a complex parameter for measuring conversion errors control are presented.
