General Information
SITRANS LR 400
The SITRANS LR 400 is a long-range FMCW radar level instrument. A liquids version (L) is
available for use in liquids storage, performing well on low dielectric liquids or sticky
materials requiring a purging unit. A solids version (S) incorporates the Easy Aimer design
for use in solids, especially conditions of extreme dust. On both versions, the narrow
antenna beam results in a sharp radiation cone, which makes the SITRANS LR 400 quite
insensitive to vessel interferences.
