The object of the study is the process of converting signals of proportional concentration of gases, pressure, humidity, temperature into a frequency signal, allowing to solve the problem of developing instruments for measuring and monitoring the gaseous medium with improved metrological indicators. The subject of the study is the static and dynamic characteristics of radio measuring transducers based on the reactive properties of transistor structures with negative resistance and the development on their basis of devices for monitoring the gaseous environment in military and civilian objects. In the process of scientific research, the regularities of the action of external factors, such as gas concentrations, pressure, humidity and temperature, on changes in the electrical properties and parameters of semiconductor structures with negative differential resistance and radio measuring sensors based on them have been established. The elements of the theory of gas-reactive, tensor-reactive, moisture-reactive and thermoset effects in field and bipolar structures have been developed. Developed mathematical models of radio measuring transducers of physical quantities. Experimental samples of radio-measuring converters for gas, humidity, pressure and temperature concentration have been developed to create a complex of radio measuring instruments for measuring and controlling a gaseous medium with a frequency output signal based on the reactive properties of semiconductor structures with negative resistance over a broad frequency range.
