Title
(EN) SYSTEM OF FLUID INSPECTION AND/OR IDENTIFICATION
(FR) SYSTEME DE CONTRÔLE ET/OU D'IDENTIFICATION DE FLUIDES
Abstract
(EN)
A method for identifying and distinguishing fluids and for recognizing contamination of a fluid, which method utilizes spectrographic analysis of control samples of known fluids (C) and then spectrographic analysis of unknown fluids (D) to generate optical signatures, finger prints and/or profiles of data and processed data relating to the relative intensities of light at selected wavelengths; and then, through comparison (E) of the various signatures, fingerprints and/or profiles, provides determinative information (F) as to contamination or non-contamination of the unknown fluids; after which appropriate operation control (G1, G2) is effected and/or exercised.
(FR)
Un procédé et un appareil permettent d'identifier et de distinguer des fluides et de reconnaître des contaminations d'un fluide au moyen d'une analyse spectrographique d'échantillons témoins de fluides connus, suivie de l'analyse spectrographique de fluides inconnus afin de générer des signatures optiques, des empreintes digitales et/ou des profils de données et des données traitées concernant l'intensité relative de la lumière à des longueurs d'ondes sélectionnées. La comparaison des différentes signatures, empreintes digitales et/ou profils fournit des informations qui permettent de déterminer si des fluides inconnus sont contaminés ou non. Une commande appropriée d'une opération peut alors être effectuée et/ou mise en ÷uvre.
