Objectives of the study of physical processes at elevated temperatures are becoming more relevant with the development of innovative technologies, development of new products and so on. Examples of areas where demand for high-temperature pressure sensors (VDD) can serve as a nuclear power complex, rocket and space technology, aviation, metallurgy, chemical industry, etc. In this case, the maximum temperature of the medium can be from 150 to 1500 ° C short-term or long-term nature. Reviewed and analyzed the features of the Airborne Division, using different physical principles of transformation. Noted that traditional Airborne Division, equipped with liquid cooling system, are of limited use, and most of them can not be used to charge objects. It is shown that the primary consideration when designing VDD is high and studies of functional materials that are used in the sensor element (SPE) for converting the high-pressure gas and liquids into an electrical magnitude. The analysis of the currently existing mono- and polycrystalline high-temperature materials and technologies form the basis of their NOI. It is noted that for the sensors of pressure pulsations and rapidly pressures promising materials are single crystal piezoelectrics: langasite and langatate.
