PSI Online Diameter-measuring Particle Size Analyzer (PSI) is an online smart industrial instrument
to measure particle sizes in an automatic and real-time mode. It consists of three parts -- main
control box, detector and installer. PSI directly measures microcosmic approximate diameter of
particles by high precision displacement sensor, then, it makes statistical analysis on measurement
results. It has strong adaptability in applications. The measurement result is intuitional, stable and
reliable.
