LABORATORY SOFTWARE PROCESS AUTOMATION Process- Refractometer iPR-Series Your eye in the pipe! Inline Process Refractometers (iPR) from SCHMIDT+HAENSCH have been used successfully in a wide range of process monitoring appli- cations for more than 35 years. Our iPRs continuously measure the refractive index and instantly determine the concentration of dissolved solids in solution and/or the mixing proportion of binary or quasi-binary liquid mixtures. The measurement is independent of turbidity, colour and absorption as well as viscosity. Over 35 years of experience and optimization, we have designed technical solutions for various demanding applications and chal - lenging process conditions. S+H IPRs perform with unmatched reliability, resolution and precision by using only highest quality components and manufacturing standards. Technological highlights of iPR measuring heads • Measurement in less than 1 second • Compact units with integrated electronics in the IP69K housing (integrated or remote display optional) • Temperature measurement within the sapphire prism ensuring the fastest and most precise temperature reading resulting in drift free temperature compensated measuring values • Stated precisions are valid within the whole temperature range • LED light source (589nm), extrem. long lifetime (100,000 hours) Due to the unique technology implemented, the iPR light source does not have to be exchanged or recalibrated during the entire life time of the instrument • Measuring sensors meet the hygienic requirements of the food and pharmaceutical industries and tolerate temperatures up to 150°C*** • Temperature compensation for individual products (e.g. Brix, Oechsle, Glycol, H 2O2) • User configurable digital switches (1 A) • Galvanic isolated 4 - 20 mA outputs* • Internal desiccant bag increasing the life span of electrical and optical components • Electronic moisture sensor within the measuring head • Process connections with VariVent (Tuchenhagen), TriClamp, APV, or in-line housing for small volumes • Known SCHMIDT+HAENSCH quality „Made in Germany“ * Except iPR Compact ** Models iPR FR2, iPR HR2 *** Only iPR FR2 Inline, immediate concentration monitoring directly within the process stream. Applications • Concentration monitoring • Product interface detection (product recovery) • Deviation from a nominal value (quality control) • Crystallization / powder or crystal dissolving monitoring • Dosage control (blending) • Impurity detection Application highlights Inline Refractometer • Monitoring of bio-extraction and fermentation process • Concentration measurement of gela- tine, glue, citric acid, lysine, lactic acid and other biological agents Pharmaceutical industry • Concentration measurement and dosing of cutting oils and lubricants • Lubricants blending control • Concentration of coolants Tobacco industry Chemical, petrochemical, chemical fibre • Quality control of chocolate, coffee, yoghurt, soya milk, honey and other food additives • Dilution or evaporation process control in juice, jam, ketchup industries • Dealcoholisation process of beer • Payment system in the wine production (sugar content - Oechsle, Brix) • Process monitoring in the pectin prod. • Control of coffee and tea extraction process • CIP monitoring, product recovery and interface detection • Concentration measurement of modified starch for sizing in paper production • Recovery process of black liquor and online testing of green liquor • Detection of hydrogen peroxide concentration • Concentration of ammonia denitration process control, etc. • Impurity detection Semiconductor, electronics industry • Brix measurement of: Cane sugar, beet sugar, starch, sugar, raw sugar refining, molasses • Monitoring of the crystallisation process • Impurity detection in condensate • Concentration measurement of starch or sweetener Food and beverage industry Sugar, starch, sweeteners Biofuels and fermentation industry • Extraction, mixing, preparation, purity testing, crystallisation and dissolution monitoring • Monitoring of chemical reactions as well as impurity detection • Quality control of final products • In accordance with Pharmacopoeia requirements • Monitoring of washing baths, flavours and fragrances control • Concentration measurement during extraction of the active ingredients • Concentration of coolants • Concentration measurement of solvents in the chemical fibre production. E.g. sulphuric acid, hydrochloric acid, phosphoric acid, caustic soda, alkali, DMF/DMSO/DMAC and other solvents • Concentration of urea during the production of fuel additive • Ammonia concentration in fertiliser production • Interface detection in the oil phase seperation Pulp and paper industry • Monitoring and purity control of sol- vents and various chemicals used for etching or cleaning in LCD display and chip manufacture. E.g. solvents, hydrogen peroxide H 2O2 concentration and dosage Mechanical processing, mining industry Electricity, energy industry Smart heads for smart solutions iPR inline sensors can be used as a stand-alone solution with inte- grated display or connected to a PLC. Using the integrated digital switches (up to 1 A), the iPRs can re-motely control pumps, valves as well as signals (e.g. visual, acoustic alarm). This feature allows a direct, real-time process con- trol and simple automations (e.g. simple dosage systems) without an additional PLC. The iPR measuring heads can be combined with various process sensors such as O 2, CO 2, pH, turbidity or conductivity to an intelli- gent sensing station. To be resistant against most chemicals, wetted parts of our smart heads are made of stainless steel, complying with regulations in food, beverage and pharmaceutical industries.The synthetic YAG or sapphire prism is both mechanically stable and chemically inert to acids, sludge and solvents. Standard CIP procedures as well as the pipe pig use are applicable and controllable.

Preferred sealing material is Viton but special sea- ling (gasket) materials are available on customer request. (e.g. Kalrez) To avoid the contact of highly concentrated acids or corrosive substances with stainless steel surface, special PTFE inline housings for the iPR are available. The preferred process connection from SCHMIDT+HAENSCH is the VariVent inline housing. The VariVent connection will handle pressure up to 10 bar and is hygienic while minimizing dead space. The iPR is also available in an intrinsically safe version. (ATEX Ex II 1G Ex ia IIC T4) For processes, where the substances cause fouling on the prism surface, a cleaning device using water, steam or solvent is available.
