ENHANCING MEASUREMENT ACCURACY UNDER NONLINEAR SENSORS

V. T. Kondratov

Abstract

The paper solves a physical quantity measurement enhancement problem under a shifted power sensor-transfer function with known and unknown values of its power exponent n. The problem is solved on the basis of a functionalalgorithmic method, used to linearize a general transfer function, existing for a digital meter, as well as of a redundant measurements method, used for automatic correction of systematic errors. It is shown, that the distinctive feature of the former method is application of respective quantities substitution formulas. The essence of the proposed methods is described. The redundant measurements equations are derived.
