Abstract
A prototype aerodynamic particle sizer (APS), developed by TSI, Incorporated, for the National Institute for Occupational Safety and Health, is described. The APS is composed of three chief modules: a sensor, a signal processor with multichannel accumulator, and a data analysis and display microcomputer. Particles pass through a thin walled orifice, and aerodynamic particle diameter is calculated as a function of the difference between particle velocity and air velocity. Sampling efficiencies for particles between 5.8 and 10.0 micrometers range from 62 to 120 percent. Experiments that show the adaptability of the APS to cyclone efficiency testing are discussed. The authors conclude that the APS is reliable, compact, easy to use, and fulfills a need for a near real time APS.
