SOPAT image-based particle measurement system

German company SOPAT (Smart Online Particle Analysis Technology) develops and sells photo-optical and image-based analysis and measurement technology that quantitatively characterises multi-phase particulate systems. In combination with the hardware, SOPAT software provides real-time analysis of particle size distribution and characteristics.

The goal is to produce tailor-made particle measurement systems that allow for the early detection of trends and efficient process optimisation. This advantage leads to cost reductions in both time and personnel, increasing product quality and reducing waste.

Measurements occur inline during the production process, so neither sampling nor dilution is necessary. This means that the sample is neither changed on the way to the laboratory, nor must production be stopped. SOPAT says that image analysis also provides a clear differentiation between different kinds of particles species. For example, bubble size can be measured separately from the ore, clay or other substance.

A wide range of probes is available to cover the range of 0.5 to 50,000 µm; however, for mining the ideal probe has a measuring range of 1–350 µm.

The probe can be directly mounted in the in-flow or the out-flow port of a flotation vessel for continuous measurement and feedback to the onsite SCADA system. Other mining applications are also possible.

To protect the probe in abrasive applications, rubber fittings or pneumatically retractable ceramic fittings are available.
