The OPTIWAVE 3500 is a 2-wire 80 GHz radar (FMCW) level transmitter for liquids in hygienic applications. It is designed for continuous, non-contact level measurement in the food and beverage as well as pharmaceutical industry. The device features a flush-mounted PEEK Lens antenna with a small beam angle and dead zone for precise measurement even in small and narrow tanks with agitators. It is equally suited for use on larger tanks, measuring distances of up to 50 m / 164 ft.

Features & Options

Product features and options depend on device configuration: Contact us to make sure that your preferred functionality can be combined in one device.

  • 2-wire, loop-powered, with HART®7
  • Flush-mounted PEEK Lens antenna (no tank intrusion)
  • Small dead zone and beam angle (8° with DN40 / 1½″)
  • TBM (Tank Bottom Management) ensures reliable measurement even in empty tanks:
  • dedicated algorithms to filter and compensate for irregular radar wave reflections that occur at tank bottom when the vessel is empty
  • allows for quick and easy commissioning of tanks regardless of their size, material or geometry
  • ± 2 mm / ±0.08” accuracy
  • Empty tank spectrum function eliminates false reflections caused by tank internals
  • Suitable for SIP (Sterilisation In Place) and CIP (Cleaning In Place)
  • Large choice of hygienic process connections
  • Large, backlit LCD screen with 4-button keypad for operation with bar magnet; no need to open the housing cover
  • PACTware™, HART® DD and DTM provided free of charge with full functionality
