Benefits

  • Maximized yield: Detect phases of your CIP process fast and avoid product loss due to precise and rapid recognition of phase changes.
  • Compact design: Benefit from installation dimensions to save space and install the phase separation device even in tightest areas.
  • Easy handling and truly maintenance-free by design: Only an annual ball lens cleaning is required, independent of CIP cycles. The innovative design without replaceable sealing materials eliminates O‑ring changes and ongoing maintenance effort.
  • Reliable measurements: The unique ball lens prevents interference due to air bubbles.
  • Simple installation: Various process connections allow for easy installation in pipes. No further configuration is necessary, since the compact device delivers measured values once it's connected to the PLC.
  • Compliance: The phase separation device complies with all relevant hygienic certifications such as 3-A, EHEDG, EU Food Contact Materials (EC) 1935/2004 and US Food Contact Materials FDA CFR 21​.

Description

The compact CUD33 turbidity device enables reliable and resource-saving CIP cleaning in food & beverage applications. It takes phase separation to the next level, ensuring maximum product output by fast and reliable detection of media change, e.g. milk/water. The 4...20 mA output can be easily connected to any transmitter or control system. Furthermore, the device offers all common process connections in phase separation applications: G1/2" threaded, Varivent and Tri-Clamp connection.

Field of application

The optical scattered light device CUD33 is ideally suited for detecting and distinguishing various products in:​

  • Phase separation of dairy products and water
  • Phase separation of yeast and water in breweries, e.g., for yeast recovery
