Phasen-Doppler-Partikel-Messsysteme mit Powersight™ Solid-State Laser

Artikelnr: PS-TM-2D

*Diese Seite ist leider nur in Englisch verfügbar.*

Phase Doppler Particle Analyzer (PDPA) systems from TSI now feature Powersight modules, the latest in solid-state laser technology. Our PDPA systems use patented techniques, cutting edge integrated optical design and lasers, and proven design features to give years of reliable, user-friendly, and cost effective service to the customers.


TSI’s Phase Doppler Particle Analyzer systems provide accurate and reliable flow velocity and particle size data from all measurement situations—from simple flows to high speed, low SNR situations. With up to 800 MHz sampling rate and photon-counting level sensitivity, only TSI electronics have the speed and versatility to handle all your PDPA measurement needs. Backed by over 25 years of producing Phase Doppler and laser Doppler systems, versatility is not only a design goal; it is built-in.

The Phase Doppler Method is based upon the principles of light scattering interferometry. Measurements are made at a small, non-intrusive optical probe volume defined by the intersection of two laser beams. As a particle passes through the probe volume, it scatters light from the beams into a multi-detector receiving probe, strategically located at an off-axis collection angle. The phase shift between the Doppler burst signals from different detectors is proportional to the size of the spherical particles.
