The in-situ probes of the Aello 1100 series are in-line sensors, made for the characterization of liquid disperse systems. The longtime experiences in research work and construction of optical sensors promoted the development of this device group, which resulted in very compact and user-friendly in-situ probes.

The probe utilizes the dynamic extinction as measuring principle for determining of indices of particle mean size and concentration. This method allows process monitoring and control in complex multiphase processes. The calculation of particle size and optical concentration takes place via different algorithms of signal evaluation.

Due to integrated digital signal processing a direct connection (adapter) to a PC by a standard RS-232 interface minimizes the hardware requirements of the Aello 1000 series. Different special accessories, like flow cell adapter, special fittings for use in pressure pipes and fittings for sterile applications complete the Aello 1000 series.
