| 摘要 |
Presented is a particle sensing system is for providing particle distribution information in a fluid flow in which thermophoretic particle movement is induced (10) towards a sensor (12) for sensing collected particles. In accordance with the present invention, the thermophoretic particle movement is in opposite direction to the direction of gravity, and the sensor (12) is located above the sensing volume. The sensor (12) comprises a series (70) of sensor elements arranged along the length direction of the elongate channel, each sensor element positioned for sensing a particular particle size. Additionally, a method providing particle distribution information in a fluid flow is presented. |
