Abstract

The study presents the results of a com-parative analysis of the metrological characteristics related to the various construction options for two-parameter measuring piezoelectric transducers with a ratiometric output. The research is carried out using simulation modeling methods. Structurally, the measuring transducer is a composite piezoelectric transformer with two degrees of freedom. The sensitive element of the transducer can be a vibrator or a coupling element between resonators. When changing the parameters of the sensing element, there is a redistribution of vibrational energy across the degrees of freedom, depending on the nature of interactions and the level of coupling in the system, the goodness of the resonators, and the degree of their natural frequencies detuning. The output signal is generated using the ratio of output voltages of two piezoelectric transformers excited at the same frequency or the ratio of output voltages from one piezoelectric transformer alternately excited at two different frequencies. Specific coupled oscillation modes in the system allow implementing the adjustable necessary sensitivity mechanism for a sensor. Appropriate methods of generating the sensor output
