Background. The object of the study are measuring converters of the output values of parametric sensors into unified signals, which are widely used in informationmeasuring and control systems, in particular, for measuring the composition of blood and biological  solutions, being the most important node of these systems in terms of providing the required metrological and operational characteristics. An important aspect is the need to ensure the independence of the result of the conversion from data in this measuring experiment, the parameters of the parametric object and the actual sensor (the invariance of the result of theconversion to these options and their uncontrolled change) the subject of the research is to find methods to build transducers with the use of the basic provisions of technical cybernetics, in particular, of the Acad. Belberov invariance principle.
Materials and methods. Proposed with the development of transducers to implement the invariance principle by the structure and / or algorithm of measuring conversion of redundancy, specifically analytical.
Results. A general structure of measuring сonverter redundancy and the corresponding mathematical Model are worked out. The considered variants of implementation of the proposed approach to the synthesis of the measuring converters.
Conclusions. The theoretical results and the experience of practical application of the developed transducers of different purposes allow to make a Conclusion About the prospects of the use of redundancy, in particular, the analytical, the construction of transducers for sensors parametric primarily to reduce bias from the influence of uninformative parameters of the studied object and sensor.
