Sensor Development
This research area focuses on the development of advanced measurement techniques to determine particle size, shape, and concentration within fluid-particle flows. Our work aims to enable precise, real‑time characterization of particulate processes across a wide range of industrial applications.
A central focus is the design and optimization of inline and online light‑extinction and light‑scattering sensors. These sensor systems will be integrated directly into industrial equipment and reactors, enabling continuous monitoring of particle kinetics and separation efficiency. Their development supports improved process control, enhanced product quality, and more efficient operation.
Some examples of sensor technologies developed are listed in the table below.
| Sensor Type | Particle Size | Particle Concentration | Measurand | Application |
|---|---|---|---|---|
| 3D LSS (Light Scattering Sensor) | 0.4 µm - 5 µm | up to 107 particles/cm3 | sphericity | dust aerosols |
| Spectral Extincton | 30 nm - 1 µm | ppm up to 30 Vol% | mean particle diameter, concentration | precipitation reactions, colloidal dispersion measurement |
| Statistical Extinction | 1 µm - 1 mm | ppm up to 30 Vol% | mean particle diameter, concentration, velocity | spray and emulsion characterization |
