Radar (FMCW) level transmitter for solids from granulates to rocks • Continuous, non-contact level measurement in/on silos, stock piles, conveyor belts etc. • 24 GHz radar, Horn or Drop antennas The OPTIWAVE 6400 is a 2-wire 24 GHz radar (FMCW) level transmitter for basic applications with solids. This radar is designed for continuous, non-contact level measurement of stones, plastic granulates, coffee beans and other products in solids processing of various industries. The level transmitter features a Metallic Horn antenna as well as PP and PTFE Drop antennas. The Drop antenna design minimizes scaling and is unaffected by the angle of repose. Hence no need for expensive antenna aiming kits or purging systems. The OPTIWAVE 6400 provides accurate and reliable readings, despite uneven product surfaces or dusty atmospheres. Due to its small beam angle and its high dynamic range, the 24 GHz radar can measure distances up to 100 m / 328 ft. This makes it a cost-effective, yet more powerful alternative to pulse radar transmitters. It also has approvals for use in hazardous areas. The radar transmitter offers flange or thread connections as well as optional antenna extensions to suit any nozzle length. It comes with HART®7 communication. • 2-wire, loop-powered, with HART®7 • Built-in configurations for different surface profiles • PP or PTFE Drop antenna: • Insensitive to product build-up • Small beam angle (4° with DN150 /6” PTFE Drop antenna) • Ellipsoidal shape and smooth surface to prevent scaling
