The paper represents the mathematical model of piezoresonance oscillator system (POS), which consists of
high- quality element- quartz resonator (QR), the element of connection and low- quality loading. Based on analyses of
main characteristics of POS in the system of MatLab, the conditions of minimization of negative impact of low- quality
loading onto personal characteristics of QR are defined. The new class of frequency- compensated piezoresonance
oscillation systems (FCPOS) based on the systems of automated frequency control (AFC) is proposed. On the example of
measuring transducer of humidity of the discrete substances, the peculiarities of building and optimization of characteristics
of primary measuring transducers (PMT) “physical parameter- frequency” based on FCPOS are studied. The possibility of
increasing the linearity of converting of PMT of present type by means of applying matrix MEMS- transducers, which
allows realizing the multi- level mode of control over the elements of connections of FCPOS, is shown.
