摘要：
This paper presents design and evaluation of a simple tool for assessing of electric charge levels on powders. The testing device uses a stackable Faraday cup arrangement for measurement of charges on size fractions of the powder under investigation. The powder is pneumatically transported through the Faraday cups column. The cups utilize specially designed sieves for separation of the powder particles by size. Additionally, the sieving membrane in the topmost cup is acoustically vibrated to help with the powder separation process
