Abstract

In this study, a new electrochemical primary transducer is considered that is designed to determine the concentration of rocket fuel components in the working area's atmosphere. This design enables continuous, automatic monitoring of the concentration of asymmetric dimethylhydrazine vapours with an accuracy up to the maximum permissible concentration. The sensitivity of the primary transducer to hydrazine hydrate was studied to determine its potential for detecting leaks of this substance in atmospheric air in various industrial areas. The designed transducer is equipped with an open-type electrode system that demonstrates high sensitivity to target components, reducing the response time to air sample delivery and significantly increasing the efficiency of analysis. Studies on the key parameters of the primary transducer have shown its suitability for integration into a gas analyser sensor. This sensor can be used in various industries involving highly hazardous chemicals. The use of these chemicals can cause significant harm to technical and engineering personnel, as well as to environmental safety in general, if the permitted safe concentrations are exceeded.
