    Chapter 2 – Product overview 2. Product overview 2.1 Vaisala Sanitary Process Refractometers PR‑43‑AC and PR‑43‑AP The sanitary refractometers PR‑43‑AC and PR‑43‑AP provide a digital interface detection system for alimentary industry. The PR‑43‑AC/AP measures the refractive index n and the temperature of the process medium.
  • Page 10 PR-43-AC/AP User Guide M212438EN-C The process medium may be hot or otherwise hazardous. Use shields and protective clothing adequate for the process medium. Do not rely on avoidance of contact with the process medium. Wear protective eyewear. Wear protective gloves. Precautions when removing a sensor from the process line : •...

  • Page 11: Installation

    If the process pipe vibrates, support the pipe. A vibrating pipe might damage the inline refractometer mounted on it. A Vaisala K‑PATENTSâ inline refractometer can be located either indoors or outdoors in most climates. However, when a refractometer is located outdoors, some basic protection against direct exposure to sunlight and rain should be provided.

    PR-43-AC/AP User Guide M212438EN-C 4. Prism wash Prism wash requires a system for wash control and diagnostics. This can be achieved with Multichannel user interface (MI) with a relay module. 4.1 Prism coating Deposit build-up on the prism surface disturbs the measurement. Anabnormally high concentration reading, an upward concentration (CONC) drift, decreased QF value or increased LED value may indicate coating.
