INTRODUCTION TO CALCULUS OF MEASURING ERRORS OF ENCODING TRANSDUCERS
Abstract
Encoding transducers are one of the widely used devices to measure the characteristics of mechanical motion in modern technics. They like other types of measuring transducers have measurement errors which are irremovable in principle and cause a discrepancy between the expected and real efficiency of the systems containing them if errors aren't being taken into account. In this paper the fundamental terms and the definitions for this problem area are introduced, the generalized design and the generalized operating principle of encoding transducers are considered and an attempt is made to analyze the causes of their measurement errors. Based on the results of this analysis it was found that the most significant source of errors is the representation of data about measured continuous values by discrete signals which is characteristic for coding transducers. Also the main parameters which influence on the formation of discretization error were identified. It can be used in further research on the formation of a corresponding mathematical model.
