The spray particle size analyzer mainly realizes the accurate measurement of droplet size through laser scattering technology. The core principle is that when the laser beam irradiates the spray droplets, the droplets will scatter, and the intensity and angle of the scattered light are directly related to the droplet size. The instrument receives and analyzes these scattered light signals, and uses Mie scattering theory or Fraunhofer diffraction theory for inversion calculation to obtain particle size distribution data.
1、 Main technical features
1. Non contact measurement: open light path design is adopted to avoid interference with the flow field, which is suitable for dynamic spray scenes;
2. High speed acquisition capability: the sampling frequency of some models reaches 10kHz, which can capture the transient spray process;
3. Intelligent correction system: multiple scattering automatic correction function ensures the accuracy of high concentration spray measurement;
4. Modular design: The split structure supports an adjustable measurement range of 1-10m, suitable for different application scenarios.
2、 Typical application areas
1. Pharmaceutical industry: Evaluate the atomization uniformity of inhalation drug delivery devices;
2. Agricultural crop protection: optimizing the droplet coverage and nozzle performance of pesticide spraying;
3. Industrial combustion: analyze fuel spray efficiency and combustion chamber atomization effect;
4. Cosmetics research and development: test the atomization fineness of spray products.
Some models, such as Winner318A, also have a three-dimensional fine adjustment detection unit and an air curtain protection device, which can work stably in harsh environments, while Bettersize2000S achieves an ultra wide measurement range of 1-2000 μ m through a Fourier optics system.
