Abstract :
The paper describes the development and design of fluidic-acoustic gas sensors, which can used in industry for in situ analysis of qualitatively known binary gas mixtures. The sensors are distinguished by high reliability, by immunity to extreme temperatures, contaminations or aggressive media and by high speed of response
