Gas sensor for determining physical characteristic of sample gas, has sensor element, which is exposed to sample gas element section
The gas sensor has a sensor element (14), which is exposed to a sample gas element section (142). The gas sensor has a protective sleeve (22), which is made of gas permeable porous metal fiber composite and surrounds the element section. The fiber material of the metal fiber composite is fixed with...

| description | The gas sensor has a sensor element (14), which is exposed to a sample gas element section (142). The gas sensor has a protective sleeve (22), which is made of gas permeable porous metal fiber composite and surrounds the element section. The fiber material of the metal fiber composite is fixed with additive, which causes the formation of a stable oxide layer on the fiber surface. The fiber material is a metal alloy with many additives e.g. aluminium, chromium, manganese, copper or noble earth metals, preferably lanthanum and cerium. An independent claim is also included for a method for the production of a sleeve for measuring gas.
Es wird ein Gassensor zur Bestimmung einer physikalischen Eigenschaft eines Messgases, insbesondere der Temperatur oder der Konzentration einer Gaskomponente eines Gasgemisches, angegeben, der ein Sensorelement (14) mit einem dem Messgas aussetzbaren Elementabschnitt (141) und eine den Elementabschnitt (142) umschließende Schutzhülle (22) aus einem zum Gasdurchtritt porösen Metalldrahtverbund aufweist. Zur Verlängerung der Standzeit des Gassensors durch Verhindern einer korrosiven Zersetzung der metallischen Schutzhülle (22) sind dem Drahtmaterial des Metalldrahtverbunds Additive beigefügt, die die Ausbildung einer stabilen Oxidschicht auf der Drahtoberfläche bewirken. |
