SITRANS LR460 (HART/PROFIBUS PA)
The SITRANS LR460 is a 4-wire 24 GHz FMCW radar level transmitter with extremely high
signal-to-noise ratio and advanced signal processing for continuous monitoring of solids up to
100 m (328 ft). It is ideal for measurement in extreme dust. 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 LR460 quite insensitive to
vessel interferences.
