Abstract

This paper presents the results of new researches of the method of sensors dynamic characteristics correction — a method of transient response signal forcing in the measuring circuit of the sensor. The efficiency of the forcing method is shown in comparison with the classical algorithm that expects the end of the transient response in the measuring circuit. The limits of the range of the method´s main parameter — a signal forcing coefficient are considered. The method is applicable for DC measurements of winding resistance of power transformers or measurements of a constant temperature of the object under step exposure to the sensor. This paper summarizes the development trends of this method of correction that is based on the iterative approach to the conversion of physical quantities. Three-point algorithm of the method of selected points is used as base algorithm for information processing. Maximum error of assessment of the asymptote of a transient response in a measuring circuit described by a first-order circuit is analyzed.
