Description
Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zur Messung einer Komponente in gasförmigen Medien mit reduzierter Leistungsaufnahme, die in einem Gasraum angeordnet ist, nach dem Oberbegriff des Anspruchs 1.The The present invention relates to a measuring device a component in gaseous media with reduced Power consumption, which is arranged in a gas space, after the Preamble of claim 1.

Durch den Aufbau des Gassensors und dessen Anordnung im durchströmenden Medium erfolgen auch hier ein hoher Energieverlust und damit eine höhere Leistungsaufnahme zur Kompensation der hohen Verlustenergie durch erzwungene Konvektion.By the structure of the gas sensor and its arrangement in the flowing Medium also take place here a high energy loss and thus a higher power consumption to compensate for the high energy loss by forced convection.
Die
Aufgabe der Erfindung ist es, einen Festelektrolyse-Gassensor, der den Partialdruck einer in einem Gasgemisch enthaltenen Komponente bestimmen kann, so anzuordnen, dass dieser durch seinen miniaturisierten Aufbau für einen batteriebetriebenen Einsatz geeignet ist und durch seine schnelle Ansprechzeit für atemzugsaufgelöste Messungen verwendet werden kann.task The invention is a solid electrolysis gas sensor, the partial pressure determine a component contained in a gas mixture, to arrange so that this by its miniaturized construction is suitable for a battery-operated use and due to its fast response time for breath-resolved Measurements can be used.
Erfindungsgemäß wird die Aufgabe durch die Merkmale des Anspruchs 1 gelöst. Hierbei wird ein Sensorelement auf kleinstem Raum untergebracht, der sich in einem wärmeisolierenden Umfeld befindet, um die zum Betrieb notwendige Arbeitstemperatur mit minimalem Energieaufwand zu erreichen und den Energieverlust durch erzwungene Konvektion, Wärmeleitung und Wärmestrahlung weitestgehend zu vermeiden.According to the invention the problem solved by the features of claim 1. Here, a sensor element is housed in the smallest space, which is located in a heat-insulating environment the operating temperature required for operation with minimal energy consumption to achieve and the energy loss through forced convection, Heat conduction and heat radiation as far as possible to avoid.
Erreicht wird dies durch die Reduzierung des Volumens des Sensorelementes sowie des Messraumes, in dem sich das Sensorelement befindet einerseits und durch die Verwendung wärmeisolierender und wärmestrahlungsreflektierender Materialien andererseits.Reached This is achieved by reducing the volume of the sensor element and the measuring space in which the sensor element is located on the one hand and by the use of heat insulating and heat radiation reflecting On the other hand.
Die Erfindung wird beispielhaft an sechs Figuren näher erläutert und dargestellt.The The invention will be explained in more detail by way of example with reference to six figures and shown.
