Smart Wide-range Measurements Using Adaptively Adjusted Sensors

Szabatin J., Platonov A. A., Melnikov V. E.

Vol. 47, nr 1

15-27

In this paper, a new class of intelligent analog-digital systems for the measurement of mechanical quantities, such as acceleration, displacement, mass size, pressure and others, is considered. The basic feature of these systems is that they employ sensors with parameters adjusted adaptively to the statistics of measured processes and disturbances. The problems of practical realization of such systems are considered. For reason of superior quality characteristics and low cost, as a reference point for the design of the proposed measurement systems, electromechanical sensors based on quartz glass technology have been chosen. Necessary modifications of conventional sensors allowing a considerable extension of the dynamic range of measuremnts without loss accuracy are proposed. Some properties of quartz glass technology are also briefly discussed.
