SITRANS LR560 overview

SITRANS LR560 is a 2-wire, 78 GHz FMCW radar level transmitter for continuous monitoring of
solids and liquids in vessels to a range of 100 m (329 ft). The plug-and-play performance is ideal
for all solids applications, including those with extreme dust and high temperatures to +200 °C
(+392 °F). The device is an electronic circuit coupled to a lens antenna and flange for quick and
easy positioning.
The main benefits of using 78 GHz over devices using lower frequency are:
● very narrow beam, so device is insensitive to mounting nozzle interference and vessel
obstructions.
● short wavelength yields very good reflection properties on sloped solids, so aiming towards
material angle of repose is usually not necessary.
The technology is very tolerant to buildup on the lens antenna, however an air purge inlet is
provided for periodic cleaning if required.
