Title (EN) PHOTOACOUSTIC GAS SENSOR UTILIZING DIFFUSION
(FR) CAPTEUR DE GAZ PHOTOACOUSTIQUE UTILISANT LA DIFFUSION
Abstract: front page image
(EN)The present invention relates to a photoacoustic gas sensor utilizing diffusion having a sensing volume and an acoustic pressure sensor volume containing an acoustic pressure sensor such that the fluid connection between the sensing volume and the acoustic pressure sensor volume restricts the flow of analyte gas therethrough but does not restrict the transmission of the photoacoustic signal therethrough.
(FR)La présente invention porte sur un capteur de gaz photoacoustique utilisant la diffusion et ayant un volume de détection et un volume du capteur de pression acoustique contenant un capteur de pression acoustique qui limite dans celui-ci le flux du gaz émanant de l'analyte, mais ne limite pas la transmission du signal photoacoustique.
