Steuma ND OLR Process refractometer The Steuma ND-OLR is a process refractometer which measures the concentraons of process liquids, as e.g. the quanty of sugar dissolved in water, the vol% mineral oil in water etc. The Steuma ND-OLR must be installed in a by-pass (12mm tubing) of a process line or tank. The Steuma ND-OLR measures concentraons based on the re- fracve index of an infrared light beam going from a sapphire prism into the process liquid. The unique opcal principle of the Steuma ND-OLR is patented. The Steuma ND-OLR has a sensivity of up to one thousandth of a per cent and is highly stable. This results in a high level of precision of the measured concentraon. An oponal connuous ultrasonic cleaning systems prevents any coang of product on the surface of the measuring prism not add- ing water, steam or any chemicals into the process liquid. The measured refracve index and liquid temperature are sent to the analyser monitor, the Steuma Master. With these values the Steuma Master calculates the concentraon using the patented 3d-calibraon matrix. During calibraon of the instrument this matrix has been defined by the refracve index of the process liquid in dependence of the liquid temperature. Applications Food and Beverage: measuring soſt drinks and juices, beer, apple- sauce, syrups, alcohol-disllaon processes, etc. Chemical and Petrochemical: Teflon plunge bath, PVA, ammonia, cooling -and lubricaon liquids, gelanes, urea, DMAC, etc. Instruction for Use See the manual & www.steuma.com Advantages • The Steuma ND-OLR can measure very low concentraon variaons at high precisions. • The measurement is not influenced by temperature variaons or fixed parcles in the process liquid, by pressure variaons, opacity or other interferences • An unique and patented ultrasonic cleaning system prevents coang of the measuring prism Safety Aspects See the manual & www.steuma.com Certificaten CE comform EN50081-1 EN50082-1 EN60065 References • Coca Cola Enterprises Nederland • Coca Cola Enterprises Belgian • AKZO Fibers • Monsanto USA
