SITRANS LR 460
SITRANS LR 460 is a 4-wire 24 GHz FMCW (Frequency Modulated/Continuous Wave) radar
level transmitter with advanced signal processing for continuous monitoring of solids up
to 100 meters. It is ideal for extreme dust and difficult applications. The Easy Aimer design
makes it easy to install the device and orient the signal towards the material angle of
repose. The high frequency signal creates a narrow emission cone, which makes the
LR 460 quite insensitive to vessel interferences.
