OPTIWAVE-M 7500
Radar (FMCW) level transmitter for liquids and solids in the marine industry
- Continuous, non-contact cargo level measurement
- 80 GHz radar, Lens antenna (flush-mounted)
- Very small beam angle for narrow tanks of various heights and shapes
- Redundant ullage indication with local display on deck
OPTIWAVE-M 7500 with DN40 / 1½" PEEK Lens antenna
The OPTIWAVE-M 7500 is a highly accurate and reliable 2-wire 80 GHz radar (FMCW) level transmitter for measuring ullage. Equipped with a heavy-duty stainless steel housing, this marine level radar is designed to withstand the roughest conditions on deck. Due to its flush-mounted PEEK Lens antenna with a very small beam angle, this FMCW radar is the optimal choice for continuous, non-contact level measurement involving narrow small or high tanks with internal obstructions. Insensitive to deposits or corrosive environments, this marine level transmitter is equally suited for oil or other liquids, slurries and pastes as well as solids.
The extremely rugged cargo radar features a backup display for redundant indication. Cargo operations may continue with a man on deck, if level information is lost on the main monitoring station. The OPTIWAVE-M 7500 level transmitter is part of the CARGOMASTER® solution for onboard tank monitoring and alarm. It holds IEC (Ex ia IIC) intrinsic safety certification as well as approvals of all major marine classification societies.
Product highlights
