LR75 LevelWave (80 GHz)  Free-Space Radar (FMCW) Transmitter

Easy liquid level measurement


The focused, small radar beam of Schneider Electric’s FMCW 80 GHz radar technology allows installations in virtually any location and tank size. The small beam angle and negligible dead zone of this FMCW radar level transmitter make it the premium choice for liquids in small and narrow tanks with internal obstructions like agitators or heating coils, as well as tanks with long nozzles. It can even measure through tank roofs made of non-conductive material.

• Easily adaptable to retrofit existing applications – can be installed close to the tank wall
• M12 cable connector option lowers labor costs with quick plug and play wiring
• Compatible with ball valves for complete process safety isolation
• Quick intuitive set-up with push buttons or PACTware™ DTM
• Compatible with WirelessHART Adapter WHA-ADP2
