The article is devoted to the development of mathematical models of engineering components and assemblies of piezoelectric sensors used to measure rapidly varying pressures and pressure pulsations of liquids and gases in a variety of products and units of rocket and space and aviation technology. Mathematical models in the form of structural models , equations , graphs and numerical values. We analyze the influence of various factors on the accuracy of the sensor. Metrology and sensor node model as a whole, allow us to determine the size and structure of the sensor errors , in order to further minimize it .

mathematical model, analysis, synthesis, an elastic member, the transfer function, the error sensor, the physical quantity of rapidly, pressure, influence factor.
