Direct insertion or bypass designs
Krüss offers two models of Process Refractometers in the PR21 series. The PR21 has been developed for direct insertion into pipes and boilers, for process monitoring, control and separation of products in such industries as chemicals, beverages, food, pulp, paper, and sugar. Installation in a pipeline or tank is simple, as no bypass is necessary. Three interfaces are available for this unit: Analogue 0/4-20 mA, Ethernet, or PROFIBUS.
The PRB21 is a basic bypass process refractometer, meeting all requirements in continuous process monitoring, filling the gap between the DR6000 series of digital laboratory refractometers and the PR21. It is cost-effective, easy to install, has a wide measurement range, and like the PR21 covers a large range of industry applications. RS-232 and analogue 0/4–20 mA interfaces are available for this unit, and PROFIBUS can be supplied upon request. For visual monitoring an optional display is also available.
