Microwave Transmitter Improves Level Measurement
Siemens’ Industry Automation Division
announced the launch of the Sitrans
LR560, described as the world’s first 78-
GHz (W Band) microwave radar level
transmitter for solids level measurement.
The Sitrans LR560 transmitter is
equipped with a newly developed lens-
style antenna and uses non-contacting
Frequency Modulated Continuous Wave
(FMCW) radar technology. The transmitter
emits a narrow 4° beam, and its high fre-
quency enables the product to emit a very
short wavelength to provide exceptional
signal reflection, even from solids with a
steep angle of repose. The high resolution
graphical interface guides the user and
expedites start-time to less than 1 minute
for accurate and reliable level measure-
ment readings without fine-tuning. The
Sitrans LR560 is available with HART,
PROFIBUS PA, or FOUNDATION Fieldbus
protocol. Programming is supported local-
ly with pushbuttons or with an infrared
handheld programmer.
