Abstract
(DE)
Die Erfindung betrifft ein Verfahren zum Detektieren von Verbrennungsgas (11) eines Heizelements (32) durch ein Erfassungsmittel (10) in einem durch ein Gehäuse (36) einer Heizvorrichtung (12) gebildeten Innenraum (34), wobei das Erkennen durch eine spektroskopische Messmethode mittels einer Spektroskopieeinheit und einen Sensorinnerhalb einer Umhausung (14) der Erfassungseinheit (10) erfolgt, sodass bei Überschreiten eines bestimmten Schellenwerts der Konzentration des Verbrennungsgases (11) im Innenraum (34) durch eine Erfassungsmittelsteuerung (19) ein Warnsignal von dem Erfassungsmittel (10) ausgegeben wird.
(EN)
The invention relates to a method for detecting combustion gas (11) of a heating element (32) by means of a detection means (10) in an interior (34) formed by the housing (36) of a heating device (12). The detection is carried out with a spectroscopic measuring method using a spectroscopy unit and a sensor within a housing (14) of the detection unit (10) such that when a specific threshold of the concentration of the combustion gas (11) in the interior (34) is exceeded, a warning signal is output by the detection means (10) by means of a detection means controller (19).

L’invention concerne un procédé pour détecter un gaz de combustion (11) d’un élément chauffant (32) par l’intermédiaire d’un moyen de détection (10) dans un espace intérieur (34) formé par un boîtier (36) d’un dispositif de chauffage (12), la détection étant réalisée par l’intermédiaire d’une méthode de mesure spectroscopique au moyen d’une unité de spectroscopie (16) et d’un capteur (18) à l’intérieur d’un boîtier (14) du moyen de détection (10) de sorte que, en cas de dépassement d’une valeur seuil déterminée de la concentration du gaz de combustion dans l’espace intérieur (34), un signal d’alerte est émis par le moyen de détection (10) par l’intermédiaire d’une commande de moyen de détection (19).
