The previous experiment was also inline monitored by photometric measurements. The pulse laser photometer used is well suited to characterize physical properties of emulsions like dispersed phase content or average droplet size [33]. The following results demonstrate that the pulse laser can not only be used in laboratory experiments but also for monitoring continuous emulsification processes.

Ultrasonic devices can also be used very effectively as powerful tools for inline monitoring of the composition of polymer blends, residence time distribution, injection-molding processes, temperature, polymer orientation, and flow instabilities. Franca et al. [59] demonstrated the sensitivity of ultrasonic waves... 

Statistical Extinction Method for the Inline Monitoring of Particle Processes... 

Abstract The object of this study is to develop a particle measurement system on the basis of the Statistical Extinction Method, which provides an inline monitoring of different particle processes. The Statistical Extinction Method determines from the mean value and root mean square deviation of a transmission signal through a particle collective, a mean particle size and a particle concentration. For the determination of particle size distribution, an advanced Statistical Extinction Method is developed and verified. This method requires the measurement of transmission signals of several light beams of different beam cross sections through a particle collective. 

In many cases, the determination of a mean particle size and particle concentration is adequate for the monitoring of particle processes. For the investigation of the fundamental processes of particle processes, such as spray drying processes, the knowledge of the particle size distribution and the particle concentration is important. For this purpose, these quantities must be measured inline. An inline monitoring of particle processes has high demands on particle measurement systems, due to high particle concentrations or process temperatures, for example. 

Already, the previous investigations and described requirements, due to the derivation of the SE-Method, cause certain specifications for a measurement setup for the SE-Sensor. The SE-Sensor is specifically designed for the inline monitoring of industrial processes. In the course of this work, these designs are implemented and verified with regard to their suitability for the application of the SE-Method for different processes.
