  3. UR24 - Optical Path 85 Brix 4 3 5 10 Brix 2 6 0 Brix 1 1 - LED SOURCE 2 - BICONVEX LENS 3 - ENTRANCE LENS 4 - PRISM 5 - EXIT LENS 6 - CCD DETECTOR

  4. In order to obtain a refractometric measure need four basic elements: • A light source (LED source) • An optical sensor (CCD sensor) • A well defined optic path (lenses and instrument geometry) • 4) A prism made in high nD material UR24 - The four basic elements 2 1

  5. UR24 - Interface detection • Threshold • Derivative

  8. UR24 Standard

  9. UR24 Long Probe with Tri-Clamp at 21mm

  10. UR24 Long Probe with Tri-Clamp at 70 mm

  11. UR24 Adaptors

  12. UR24 - Installation examples on line by pass

  13. UR24 - Installation examples pump on boule

  14. UR24 - Special plug for selfcleaning Each product has its own optimal speed for prism selfcleaning Changing the clearance height allows to have the optimal cleaning for each product

  15. UR24 - Cleaning systems • special plug with washing • special plug with mechanical cleaner

  16. UR24 - Cleaning systems • special plug with mechanical cleaner and washing • washing on pipe • washing on tank

  17. UR24 - User configuration • nD - concentration • nD - temperature T (°C) 1,38 30 20% in water 20 nD 10 1,33 8 16 25 33 42 50 0 1,30 1,40 nD % weight/weight Instrument takes into account typical behaviour for nD Default configuration: sucrose solution curves

  18. UR24 - User configuration 1st STEP: at 20°C fixed temperature find the relationship between the concentration and the refraction index. 2nd STEP: at fixed concentration find the relationship between the corrections, you have to add to the 20°C value and the temperature Product sample 3rd STEP: transfer data in the UR24 refractometric unit Termostating Unit

  19. UR24 - User configuration • REFRACTION INDEX-CONCENTRATION configuration Found the relationship between concentration and nD at seven different values of concentration at 20 °C for desired product

  20. UR24 - User configuration • TEMPERATURE COMPENSATION configuration Measuring the refractive index at three different concentrations at three different temperatures, insert the errors in temperature table (difference between read values of each concentration at that temperature and at 20°C)
