Abstract

A significant place among structural methods to increase the accuracy of measuring converters  occupy iterative methods of error correction based on a well-developed in mathematics the theory of iterative methods. At the same time, the measurement technique is very widely used various integrating converters, due to their advantages such as high accuracy, noise immunity and sensitivity, simplicity, reliability, low cost, etc. Combining methods of integrating conversion and additive iterative correction of errors has generated a method called by the author iteratively integrating conversion method and devices using this 
method – iteratively integrating converters. Many of iteratively integrating converters possess high metrological parameters. Generalized structural scheme of the measurement converter which uses iteratively integrating conversion method is described. Analysis of its conversion equation and errors for two cases: first one – where the output value Y = Y (t) is not a constant, while the input values X, Z1, Z2 are constant and second one – where the input value X = X(t) and output value Y=Y(t) are not constant, while the input values Z1, Z2 are constant, were produced. Basic expressions for the calculation are listed.
