UNITÉ DE MESURE NON DESTRUCTIVE DE LA CONCENTRATION DE GAZ DANS DES RÉCIPIENTS SOUPLES SCELLÉS ET LIGNE DE REMPLISSAGE ET/OU D'EMBALLAGE AUTOMATIQUE UTILISANT UNE TELLE UNITÉ
The present invention relates to a non-destructive measurement unit of the gas concentration in sealed containers, as well as to an automatic filling and/or packaging line using such a unit. In particular, the present invention relates to a non-destructive measurement unit of the gas concentration in flexible containers at least partially made of optically transparent material, comprising at least one light source (11) for emitting a light beam at a wavelength tunable with an absorption wavelength of a gas contained in the sealed flexible container (30, 30'), the at least one light source (11) being positioned in such a way as to direct the light beam towards at least one inspection area (20)； at least one detector (12) positioned in such a way as to detect at least a portion of the beam emitted by the light source (11) once passed through the inspection area (20) and output data representative of an absorption spectrum of said gas resulting from the passage of the light beam through the inspection zone (20)； means (50, 50') for generating a head space (32) of predefined width into the sealed flexible container (30, 30') and is characterized in that said means (50, 50') for generating a head space (32) are adapted to advance the sealed flexible container (30, 30') by an advancement path (A) which crosses the inspection zone (20), the means (50, 50') for generating a head space (32) being further adapted to maintain the predefined width of the head space (32) during the advancement of the sealed flexible container (30, 30') along the entire advancement path (A).La présente invention concerne une unité de mesure non destructrice de la concentration de gaz dans des récipients scellés, ainsi qu'une ligne de remplissage et/ou d'emballage automatique utilisant une telle unité. En particulier, la présente invention concerne une unité de mesure non destructrice de la concentration de gaz dans des récipients souples au moins partiellement réalisés en un matériau optiquement
