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 minimises scaling and is unaffected by the angle of repose. Hence no need for expensive antenna aiming kits or purging systems.
