Background. The expansion of the working temperature range of piezoelectric sensors and the improvement of their metrological characteristics, especially when operating in harsh environments under the impact of non-stationary temperature, are among the urgent tasks of the development of sensor-transforming equipment. Measurement of the dynamic pressure of such liquids as oxygen and hydrogen, characterized by a powerful and rapidly changing temperature effect in the range from minus 253 to 200 °C, which causes temperature transients in the construction of piezoelectric sensors and, consequently, an increase nonelectric values input er-rors in transient processes.
Materials and methods. The authors researched a possibility of reducing the temperature error of the dynamic pressure measurement by piezoelectric sensors.
Results. The article adduces a functional block diagram of a piezoelectric dynamic pressure sensor with a temperature error correction circuit of a piezoelectric element, and the functioning principle thereof. The work also shows experimentally determined time dependencies of output signals of a piezoelectric sensor under thermal shock exposure to the working environment.
Conclusions. The results show the possibility of correcting errors of the tempera-ture of the piezoelectric dynamic pressure sensors, caused by exposure to static tem-peratures and thermal shocks, by using the electric capacitance of a piezoelement’s equivalent circuit as a temperature-indicating parameter.

Key words

piezoelement, thermal shock, equivalent circuit, conversion coefficient, temperature error correction.
