| 摘要 |
The present invention relates to a sensor arrangement, in particular for detecting gas emissions in the exhaust gas of a motor vehicle with an internal combustion engine, comprising a gas line (12) and an analysis chamber (14) which is bounded by a housing (16) and is fluidically connected to the interior of the gas line (12) by means of an inlet (18) and an outlet (20), wherein the analysis chamber (14) is at least partially arranged outside the gas line (12), and wherein a sensor (28) is arranged in the analysis chamber (14) in such a manner that the sensor is outside the gas line (12). The invention provides at least one cooling element (32) which is arranged in a region between the gas line (12) and the sensor (28). This makes it possible to operate the sensor (28) at temperatures below the exhaust gas temperature. |
