Background. The object of the study is piezoelectric acoustic pressure sensors. The subject of the research is the modeling of piezoelectric sensors operating under a thermal shock effect of the working environment with the temperature of minus 180 degrees Celsius. The aim is to create a mathematical model of the sensor
Methods. At construction of the mathematical model the authors used the methods of generalized operational calculus.
Results. The article offers the mathematical model of piezoelectric transducero peration in conditions of the thermal impact of the working environment. A comparison of the results of a field experiment and mathematical modeling confirms the efficiency of the proposed model.
Conclusions. The results can be used in the development of piezoelectric sensors intended for operation at non-stationary temperatures of the working environment and under thermal shock effects.

Key words

piezoelectric sensor, acoustic pressure, thermal shock, mathematical model, impulse response function
