ANNOTATION Ornatskyi D.P. Methods and facilities of improving the metrological characteristics of remote measurements of mechanical magnitudes. – Manuscript. Dissertation for obtaining the scientific degree of Doctor of Technical Sciences by the specialty 05.11.01 – Devices and Methods of Mechanical Values Measurement. – Odessa Academy of Technical Regulation and Quality, Ukraine, Odessa, 2015. Dissertation is devoted to the solution of important scientific and technical problems of development of analog interfaces for remote measurement of mechanical magnitudes with improved metrological and technical-economic characteristics. A new intelligent interface for remote measurements of mechanical magnitudes with improved metrological characteristics has been developed. A new iterative integrating converters with dynamic storage devices have been developed. New methods for correcting systematic component of error, which provide more complete reduction in exposure of destabilizing factors have been developed. Mathematical models of processing frequency signals for remote measurement of mechanical magnitudes using the analog interface, which compensate for the error from the action of destabilizing factors, have been developed. The method of automatic correction systematic inseparable component of the error measurement of mechanical magnitudes on the basis of analog interfaces for bridge and thermoelectric sensors has been developed. New intellectual instrument transducers of mechanical magnitudes with differential-parametric sensor, which improves low-frequency noise suppression ratio (flicker noise), have been developed. The method for remote measurement of mechanical magnitudes with frequency modulation, which increases the high-speed performance and the rejection ratio the low-frequency noise (flicker noise), has been developed. Keywords: intellectual interface, noise immunity, N-channel filters, instrumentation amplifiers with differential current inputs, broadband systems of phase-locked loop.
