Benefits
Graphical local user interface (LUI) makes operation simple
with plug-and-play setup using the intuitive Quick Start Wizard
LUI displays ec,ho profiles for diagnostic support
25 GHz high frequency allows for small antennas for easy
mounting in nozzles
Insensitive to mounting location and obstructions, and less
sensitive to nozzle interference
Short blanking distance for improved minimum measuring
range to 50 mm (2 inch) from the end of the antenna
Communication using HART, PROFIBUS PA,
or FOUNDATION Fieldbus
Process Intelligence signal processing for improved
measurement reliability and Auto False-Echo Suppression
of fixed obstructions
Programming using infrared Intrinsically Safe handheld
programmer or over a network using SIMATIC PDM, Emerson
AMS, or Field Device Tools, such as PACTware or Fieldcare
via SITRANS DTM
Functional Safety (SIL 2). Device suitable for use in
accordance with IEC 61508 and IEC 61511
3 mm (0.118 inch) accuracy in accordance with IEC 60770-1

Application
SITRANS LR250 includes a graphical local user interface (LUI)
that improves setup and operation by including an intuitive
Quick Start Wizard, and echo profile displays for diagnostic
support. Startup is easy using the Quick Start wizard with a
few parameters required for basic operation.
The 25 GHz frequency creates a narrow, focused beam allowing
for smaller horn antenna options and decreasing sensitivity to
obstructions.
SITRANS LR250’s unique design allows safe and simple
programming using the Intrinsically Safe handheld programmer
without saving to open the instrument’s lid.
SITRANS LR250 measures superbly on low dielectric media,
and in small vessels, as well as tall and narrow vessels
