Abstract

Acoustic sensor determining the composition of a gaseous mixture. According to the invention, the resonators used 10, 12-11, 13 resonate in flexion and are such that the response of the sensor is different for each of the components of the mixture. The sensor is then sensitive to the composition of the mixture. Application to determining the composition of air/petrol mixtures.
