Pi Sentinel PRO

Dynamic Image / Particle Shape Analyzer

Principles of Operation

Particles are suspended homogeneously in a carrier liquid. They pass through a thin flow cell in the optical path. Light is transmitted through the flow cell, thus projecting silhouettes of the particles onto a high-resolution camera sensor. The high frame rate and high resolution of the camera combined with a high-speed host computer enables the characterization of thousands of particles per second in real-time. This technique is ideal for applications where shape, not just diameter, is critical information for predicting raw material performance.


Benefits of the Pi Sentinel PRO

As a result of the improvements, the benefits are:

  • Higher speed data transfer rate, up to 127 frames per second rated digital camera with up to 5 MPs resolution, captures live images of thousands of particles.
  • Over 30 shape parameters are recorded, including circularity, ellipticity, opacity, mean diameter, smoothness, aspect ratio, fiber length and many more.
  • All analyzed particles have thumbnail images saved for post-run viewing and shape analysis, both in grey scale and binary views.
  • Ability to compare different analyses via histogram overlays for all analyzed shape parameters.
  • Scatter plot correlates two shape measurements and can be utilized as a process quality control criterion as an at-line application within unit operations.
  • Unique and powerful software permits the use to simplify data processing to a pass/fail reporting or choose to extend data analysis to a full suite of post processing image and shape analysis reports
