OPTIWAVE 5400 Level Transmitter

The OPTIWAVE 5400 is a 2-wire 24 GHz radar (FMCW) level transmitter for liquids in basic process applications. It is particularly designed for continuous, non-contact level measurement in municipal water and wastewater applications. It can be equipped with a polypropylene drop antenna for condensing atmospheres and corrosive media but also features metallic gorn antenna options. Furthermore, its high dynamic range, the 24 GHz radar can measure distances up to 328 feet (100 meters).

• continuous level measurement in closed tanks or in the open air
• -58 to 266˚F (-50 to 130˚C)
• -1 to 16 barg (-14.5 to 232 psig)
• ±2 mm (±0.08″) accuracy
• antenna extensions to suit any nozzle length
• empty tank spectrum function eliminates false reflections from tank internals

The OPTIWAVE 5400 provides accurate readings even in processes with fast changing levels, in closed tanks, or in the open air (dams, rivers, etc.). This level transmitter can replace radars in basic applications requiring higher accuracy. It offers flange or thread connections as well as optional antenna extensions to suit any nozzle length. It is approved for hazardous areas and comes with extensive device diagnostics (according to NE 107) as well as HART 7 communication.

Features of the OPTIWAVE 5400 Level Transmitter*

• 2-wire, loop-powered, in addition to HART 7
• polypropylene drop antenna:
  • insensitive to condensation
  • small beam angle (5˚ with DN150 / 6″ drop antenna)
  • ellipsoidal shape and also smooth surface to minimize scaling
  • polypropylene flange plate protection as well as cladded antenna extensions for corrosive media
  • new DN100 / 4″ drop antenna for distances up to 262.5 feet (80 meters)
• 316L metallic horn antenna with optional purging system
• TBM (Tank Bottom Management) also 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
• large choice of flange as well as thread connections
• large, backlit LCD screen with 4-button keypad for operation with bar magnet, so there’s no need to open the housing cover
• PACTware, HART DD, and HART DTM, which are free of charge with full functionality
• extensive device diagnostics according to NAMUR NE 107
• SIL 2/3 certification for safety-related applications
• 3-year warranty
