20100282006 | DEVICE FOR CHARACTERIZING A SIZE DISTRIBUTION OF ELECTRICALLY-CHARGED AIRBORNE PARTICLES IN AN AIR FLOW - The invention relates to a device that can reliably characterize a size distribution of electrically-charged airborne particles in an air flow under both stationary conditions and transient conditions. The device comprises a particle charging unit, a first particle precipitation unit located downstream of the particle charging unit, a second particle precipitation unit located downstream of the first particle precipitation unit, and a data evaluation unit. The first particle precipitation unit is arranged to partially reduce the concentration of electrically-charged airborne particles having a size larger than a first particle size limit, and to generate a first output signal corresponding to the precipitation of electrically-charged airborne particles inside the first particle precipitation unit. The second particle precipitation unit is arranged to precipitate substantially all entering electrically-charged airborne particles, and to generate a second output signal corresponding to the precipitation of electrically-charged airborne particles inside the second particle precipitation unit. The data evaluation unit is arranged to calculate, based on the output signals of the particle precipitation units, a particle number concentration and an average diameter of airborne particles larger than the lower particle size limit. The device enables the simultaneous generation and recording of output signals, and consequently an immediate determination of the particle number concentration and the average particle diameter at any instant. | 11-11-2010 |
