Title (EN) OXYGEN CONCENTRATION MEASURING DEVICE
(FR) DISPOSITIF DE MESURE DE CONCENTRATION D'OXYGÈNE
Abstract:
(EN) An oxygen concentration measuring device (100) adapted for determining an oxygen concentration of a gas in a sample volume (304) is provided. An optical device is used for irradiating the sample volume (304) containing oxygen with a first UV radiation intensity (301), at least one wavelength of which is close to a spectral absorption line of oxygen. A magnetic field generator (103) is adapted for applying a magnetic field (303) at the sample volume (304) and a UV light detector (102) is adapted for measuring a second UV radiation intensity (302) coming from the sample volume (304). The oxygen concentration in the sample volume (304) is determined on the basis of the applied magnetic field (303) and the measured second UV radiation intensity (302).
(FR) L'invention concerne un dispositif de mesure de concentration d'oxygène (100) conçu pour déterminer la concentration en oxygène d'un gaz dans un volume d'échantillon (304). Un dispositif optique est utilisé afin d'illuminer le volume d'échantillon (304) contenant de l'oxygène selon une première intensité de rayonnement UV (301) dont au moins une longueur d'onde est proche de la ligne d'absorption spectrale de l'oxygène. Un générateur de champ magnétique (103) est conçu pour appliquer un champ magnétique (303) au niveau du volume d'échantillon (304), et un détecteur de lumière UV (102) est conçu pour mesurer une seconde intensité de rayonnement UV (302) venant du volume d'échantillon (304). La concentration en oxygène du volume d'échantillon (304) est déterminée en fonction du champ magnétique (303) appliqué et de la seconde intensité de rayonnement UV (302) mesurée.
