| titleOfInvention | Device for characterizing the evolution over time of a size distribution of electrically-charged airborne particles in an airflow |
| abstract | A device is presented that is capable of recording the evolution over time of the characteristics of a size distribution of electrically-charged airborne particles in an airflow. The device comprises an air inlet, a particle charging unit, a concentration variation section, a particle sensing section and a data evaluation unit. Specifically, the particle sensing section of the device generates at least two serially obtained measurement signals I 1 and I 2 from which the data evaluation unit can infer values for both the average particle diameter d p,av and the number concentration N of the size distribution of electrically-charged airborne particles. Reliable values can be obtained for N and d p,av under both stationary conditions and transient conditions with respect to the characteristics of the particle size distribution due to the condition that the change of the inferred average particle diameter d p,av with respect to a reference particle diameter d p,ref is bounded by a set maximum change. This imposed condition markedly reduces scatter in the inferred values for dp,av and N as a function of time, while still allowing transient characteristics with respect to both N and d p,av to become visible in the course of time, without having to rely on averaging procedures and/or device hardware adaptations. |
