Ultrasonic extinction provides outstanding performance for in-line and on-line particle size analysis of suspensions and emulsions. One of the major benefits is the ability to operate in highly concentrated mediums, which typically come along with wet process stages. A solid content between 5 and 50 % by volume is a typical range of concentration. These are perfect conditions for OPUS, which even may be applied at concentrations up to 70 % by volume – typical for paste-like particulate systems.

Using sound waves instead of light waves, analysis of suspensions or emulsions is independent of transparency and may be conducted in totally opaque disperse matter like water droplets in crude oil, mineral slurries, or even carbon particles in liquid pitch. Paints, sugar pastes, or pharmaceutical suspension also belong to the main field of application. Ultrasonic extinction allows for a rugged and robust probe design that resists typical process conditions such as high temperatures, pressures or aggressive media, and abrasive materials.
