The Phase Doppler Particle Analyzer (PDPA) analyzes drop size, velocity and volume flux measurements collected with Phase Doppler Interferometer (PDI) instruments. Together, these phase Doppler interferometry instruments provide the most detailed information of the spray characteristics by characterizing each droplet that passes through the probe volume and building up accurate ensemble statistics.
Further analysis with the PDPA allows combination of the information from the many individual data points to provide volume flux and area weighted average spray pattern statistics. Spraying Systems Co. primarily uses PDPA-Powersight. PDPA systems with PowerSight modules provide accurate spray data across all measurement situations.
