The fiber optic transmitting probes are particularly designed for phase doppler particle analyzer (PDPA) measurements, to get siultaneous droplet size and velocity data from sprays.
The large fringe spacing and measuring volume generated from a transmitting probe are ideal for small droplet size range. The transmitting probe can also be equipped with a beam expander or contractor (XPD50-E or XPDN50-I), to expand the droplet size range.
The table below outlines the different types of fiber optic probes available. Select the one most appropriate for your requirement:
