Phase Doppler Anemometer (PDA) - FlexPDA

Simultaneous measurement of particle diameter and flow velocity is possible. It can measure one-dimensional or two-dimensional flow velocity, and mapping measurements are also possible.

The PDA (Particle Dynamics Analyzer) is also well known as PDPA (Phase Doppler Particle Analyzer) and PDI (Phase Doppler Interferometer), and it has established itself as a measurement method for simultaneous measurement of particle size and flow velocity. The PDA is an extension of the laser Doppler anemometer (LDA), and both PDA and LDA are optical technologies that perform ideal non-contact point measurements in a wide range of fluid dynamics applications. It is optimal for measuring the shape and velocity of particles emitted during spraying and fuel injection. 【Main Features】 - Factory-calibrated optical system for light transmission - User-friendly optical fiber receiving probe - Wide particle size measurement range from 1 to 500 μm - Sophisticated signal processor compatible with diverse applications - Advanced, versatile, and user-friendly software - Automatic phase calibration function to improve particle size measurement accuracy - Optical mount applicable to many PDA applications - Usable as a standard backscatter LDA measurement - Expandability to other solutions
