SITRANS LR460

SITRANS LR460 is a 4-wire, 24 GHz FMCW (Frequency Modulated/Continuous Wave) radar
level transmitter for continuous monitoring of solids in silos to a range of 100 meters (329
ft). It is ideal for applications with extreme dust and high temperatures to +200 °C (+392 °F).
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.
SITRANS LR460 is available with an optional air purge connection for cleaning the interior of
the antenna.
Programming
SITRANS LR460 carries out its level measurement function according to the set of built-in
parameter tables. You can make parameter changes via the Siemens handheld programmer,
a PC running SIMATIC PDM or other similar software packages.
Approvals and certificates
SITRANS LR460 is available with General Purpose approval, or approval for hazardous areas
containing dust. For details see Approvals (Page 129).
System implementation
SITRANS LR460 supports HART communication protocol, or PROFIBUS PA (optional), and
SIMATIC PDM software.
