Title (EN) MEASURING DEVICE AND METHOD FOR CLEANING CONTAMINATED AREAS OF A MEASURING DEVICE
(FR) DISPOSITIF DE MESURE ET PROCEDE DE NETTOYAGE DES ZONES DE CONTAMINATION D'UN DISPOSITIF DE MESURE
(DE) MESSVORRICHTUNG UND VERFAHREN ZUR REINIGUNG VON KONTAMINATIONSBEREICHEN EINER MESSVORRICHTUNG
Abstract:
(EN) The invention relates to a measuring device comprising a measuring apparatus especially for gaseous samples and a sample input device by means of which samples can be introduced into the measuring device. To improve such a device in such a way as to ensure that the measurement and/or analysis results of the measuring apparatus are not influenced by possible contamination, the invention provides for the sample input device to be fitted with a cleaning device for cleaning contaminated areas of the sample input device by transforming impurities in said contaminated areas by a chemical reaction, and for the reaction products to be removed from the sample input device.
(FR) L'invention concerne un dispositif de mesure comprenant un appareil de mesure pour échantillons en particulier gazeux et un dispositif d'introduction d'échantillons au moyen duquel les échantillons sont amenés à l'appareil de mesure. Pour améliorer un tel dispositif de façon que les résultats de mesure et/ou d'analyse de l'appareil de mesure ne subissent pas l'influence d'éventuelles contaminations, il est proposé que le dispositif d'introduction d'échantillons soit pourvu d'un dispositif de nettoyage servant à nettoyer les zones de contamination de ce dispositif d'introduction d'échantillons, ce nettoyage consistant à transformer les impuretés se trouvant dans les zones de contamination par réaction chimique, et que les produits de réaction formés soient évacués du dispositif d'introduction d'échantillons.
(DE) Um eine Meßvorrichtung, umfassend ein Meßgerät für insbesondere gasförmige Proben und eine Probeneinlaßvorrichtung, durch welche die Proben dem Meßgerät zuführbar sind, derart zu verbessern, daß durch eventuelle Kontaminationen die Meß- und/oder Analyseergebnisse des Meßgeräts nicht beeinflußt werden, wird vorgeschlagen, daß die Probeneinlaßvorrichtung mit einer Reinigungseinrichtung zur Reinigung von Kontaminationsbereichen der Probeneinlaßvorrichtung mittels Umwandlung von Verunreinigungen in den Kontaminationsbereichen durch chemische Reaktion versehen ist und daß die Reaktionsprodukte aus der Probeneinlaßvorrichtung abführbar sind.
