Patent ID: 7704356

Claim:
A gas sensor array, comprising: a combination of an electrochemical gas sensor and an electrochemical gas generator, the combination including a housing with said electrochemical gas sensor surrounded by said housing except at a gas sensor opening area above a measuring electrode of the gas sensor, said sensor opening area being defined by a housing edge, said gas sensor opening area being fully in direct contact with an environment of the array; and a gas channel structure including a gas channel having a length of up to 30 mm extending from a gas generator opening to a channel discharge opening at said gas sensor opening area above said measuring electrode of the gas sensor, wherein said gas channel structure has a cross-sectional area of 0.2 mm 2 to 5 mm 2 and extends over a portion of said gas sensor opening area and the measuring gas from the environment of the gas sensor has free access to the measuring electrode through said gas sensor opening area that said gas channel structure does not extend over with said gas sensor opening area that said gas channel structure does not extend over directly in contact with the environment of the gas sensor array.
