Optical particle sensors, especially exhaust gas sensors |
| abstract |
The present invention relates to a particle sensor for detecting particles in a measuring gas flow, in particular soot particles in an exhaust gas channel of a burner or internal combustion engine, said particle sensor for generating or supplying laser light (10). means, means for focusing laser light (10), and means for detecting or transmitting thermal radiation, said particle sensor (16) locating an area (16.1) exposed to the measurement gas that is not exposed to the measurement gas , having at least one optical inlet 40 separating it from the area 16.2 opposite the measuring gas. Means for generating or supplying laser light 10 and/or means for detecting or transmitting thermal radiation are arranged in the region 16.2 opposite the measuring gas. The present invention is characterized in that a particle sensor (16) draws a partial flow (321) from the measured gas flow and supplies it to a laser focus (22), further fluidically shielding an optical inlet (40) against said partial flow (321). do it with |
