Overview

The OPTIWAVE 7500 is a 2-wire 80 GHz radar (FMCW) level transmitter for demanding liquid applications involving narrow tanks with long nozzles and internal obstructions like agitators or heating coils. Its very small beam angle and negligible dead zone make this FMCW radar the optimal choice for continuous, non-contact level measurement in both extremely small and very high tanks (up to 100 m / 328 ft). The level transmitter is even able to measure through tank roofs made of non-conductive materials. Its PEEK and PTFE Lens antennas are insensitive to deposits and well suited for corrosive environments. As the antennas are flush-mounted, there is no intrusion into the tank.

  • 2-wire, loop-powered, with HART®7
  • Flush-mounted PEEK or PTFE Lens antennas (no tank intrusion)
    • Insensitive to deposit
    • Small dead zone and beam angle (4° with DN70 / 2¾″ Lens antenna)
    • PEEK or PTFE flange plate protections as well as a PEEK thread protection for corrosive media
    • 112 mm / 4.4″ antenna extension for long nozzles
  • Empty tank spectrum function eliminates false reflections caused by tank internals
  • ±2 mm / ±0.08″ accuracy
  • Large range of flange and thread 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
  • Extensive device diagnostics acc. to NAMUR NE 107
  • SIL 2/3 certified for safety-related applications
  • 3-year warranty
