Title (EN) DETECTION OF BLOCKAGE IN A POROUS MEMBER
(FR) DÉTECTION DE BLOCAGE DANS UN ÉLÉMENT POREUX
Abstract:
(EN) A method of detecting at least a partial blockage in a porous member separating an inner chamber of a device having a gas sensor responsive to an analyte positioned within the inner chamber and an ambient environment includes emitting pressure waves within the inner chamber and measuring a response via a sensor responsive to pressure waves positioned within the inner chamber.
(FR) L'invention concerne un procédé de détection d'au moins un blocage partiel dans un élément poreux séparant une chambre interne d'un dispositif comprenant un capteur de gaz sensible à un analyte placé à l'intérieur de la chambre interne et un environnement ambiant qui comprend l'émission d'ondes de pression à l'intérieur de la chambre interne et la mesure d'une réponse via un capteur sensible aux ondes de pression placé à l'intérieur de la chambre interne.
