Impactor, for making fine dust, dirt and particle measurements, has a vibrating quartz crystal attached to the impact plate so that in situ measurements of the weight of deposited particles can be made

摘要

Impactor with an impact plate onto which a classification nozzle is directed. The impact plate (10) captures particles of a certain size from within a jet of liquid directed at it. The plate has a vibration quartz (26) mounted on it which permits in-situ measurement of the weight of the trapped particles.
