PRIMARY CONVERTERS FOR OPERATIONAL GAS ANALYSIS
PURPOSE. The work is aimed at creating a primary converter for mobile highly sensitive gas analysis sensors. On the example of ozone registration, the main requirements for basic sensors are presented. Metal oxides are shown to be the optimal composition of the sensitive layer. METHODS. Air contaminants are studied by sampling and subsequent analysis in laboratories, which is laborious, time consuming and, consequently, necessitates the development of rapid and high-precision methods for quick determining the composition of gases on the sites. FINDINGS. The basic design and manufacturing technology of thin-film sensors for oxidizing and reducing gas analysis have been developed. The size of the crystal and its weight are minimized, ensuring minimal inertia and power consumption. Manufacturing technology allows obtain sensors, sensitive to various gases in the individual state and mixtures. RESEARCH APPLICATION FIELD. The implementation of basic designs and technologies for manufacturing sensors and gas modules based on them is planned at production facilities. The autonomous sensor must be equipped with a battery and a wireless transmitter to communicate with the dispatch service or with the environmental monitoring service. The proposed sensors will be produced in an explosion-proof design in accordance with the requirements presented in this work. CONCLUSIONS. Based on mobile gas analysis sensors, it becomes possible to create a monitoring system using GLONASS in order to quickly respond to emergencies; reduce the ecological burden on the environment; provide staff safety; independent warning about emergency situations when working with toxic and explosive gases.
