SOLUTION FOROEMK-Patents has used its process refractometerexpertise to develop a light,compact style refractometer modelwith rugged industrial durability anddependability. K-Patents Sanitary OEMRefractometer PR-33-AC is designed tomeet the needs of original equipmentmanufacturers (OEMs) and integratorsserving beverage, dairy and foodprocessing industries.The Sanitary OEM Refractometer hasa measurement range of 0 to 100Brix and provides a 4–20 mA outputsignal proportional to the temperaturecompensated Brix value for real-timeprocess control.The Sanitay OEM Refractometer sensoris installed in the main processing lineand no by-pass arrangements arerequired. The sensor is angle mountedin the outer corner of the pipe benddirectly or through a flow cell or aSanitary clamp. This way the best fl owconditions and self-cleaning effect canbe achieved. The sensor can also bemounted with a Varivent® connection.The Sanitary OEM Refractometer isSanitary 3-A approved and EHEDGtested to meet the highest hygienerequirements of food production. It withstandsthe rigors of food processing suchas process temperatures up to 130°C(265°F), CIP and SIP processes andcleaning and rinsing of facilities.The Sanitary OEM Refractometer isfactory calibrated to measure Brix andtemperature in standard units. EachSanitary OEM sensor has identical calibration.Because of this, the SanitaryOEM sensors can be freely inter changedwithout optical recalibration or parameterchanges. The Sanitary OEM Refractometerdoes not require any recalibrationor regular maintenance.Wiring the Sanitary OEM Refractometerto a control loop is as simple as plugginga connector into the receptacle.IN-LINEINSTALLATION2.5 inch Sanitary clamp2.5 inch Sanitary clampand fl ow cell2.5 inch Sanitary clampand fl ow cellVarivent® connectionACCURATEOPERATIONK-Patents Sanitary OEM RefractometerPR-33-AC provides truly accuratemeans for measuring Brix. The SanitaryOEM determines the concentration ofdissolved solids by making an opticalmeasurement of a solution’s refractiveindex n D. The measurement is automaticallytemperature compensated.The measurement accuracy is n D+0.0002 and repeatability is n D+0.0001, which result in repeatabilityof +0.05 Brix. The same accuracy andrepeatability are provided across thefull measurement range of 0–100 Brix.The output values of the sensor aretransmitted through a 4–20 mA outputand an Ethernet connection by using aUDP/IP protocol.The measurement is not infl uenced bybubbles, particles, sugar crystals, seeds,fi bres, color or temperature and pressurechanges in the process medium.K-Patents' manufacturing process is ISO9001 certifi ed. K-Patents also sup portsthe verifi cation within the user's ownquality system. The calibration and accuracyof the Sanitary OEM Refractometercan be easily verifi ed on-site with thecertifi ed refractive index liquids.

eyflei-DDyde.etay,eDIGITAL MEASUREMENTPRINCIPLELightsourceLight sourcePrismPrismRefl ected lightCriticalangleThe light source sends light againstthe interface between a prism and theprocess solution, where the rays meetthe surface at different angles.ProcessmediumOpticalimageThe angle corresponding to the shadowline is called the critical angle of totalinternal refl ection. This angle is a functionof the refractive index and thereforethe con cen tration of the solution.DATA LOGGINGVIA ETHERNETK-Patents Sanitary OEM RefractometerPR-33-AC is the most advanced refractometeron the market since it includesan Ethernet based communicationssolution. This allows connection anddata download to a computer. Realtimemeasurement data and diagnosticinformation may be obtained throughthis interface, and this makes it alsoa valuable service tool for parameterchanges and software updates.Any computer with a standard Ethernetconnection can be confi gured to viewand download data from the sensor byusing a standard web browser.sn-reSolutionRefracted lightDepending on the angle, some raysundergo a total internal refl ection. Therest of the light is refracted into theprocess solution.Thus an optical image with a dark sectorand a light sector is created.Critical angleA CCD-camera detects the opticalimage. The image is transformed pointby-pointinto a digital signal. Digitalsignal processing is used to locate theexact shadow line position and to determinethe refactive index n D.A built-in temperature sensor measuresthe temperature T on the interface ofthe process liquid. The sensor convertsthe refractive index n Dand temperatureT to Brix units.The diagnostics program ensures thatthe measurement is reliable.
