Overview
SITRANS LR250 is a 2-wire, 25 GHz pulse radar level transmitter
for continuous monitoring of liquids and slurries in storage and
process vessels including corrosives or aggressive materials, to
a range of 10 m (32.8 ft) or 20 m (66 ft) when used in a stilling
pipe.
■
Benefits
• Threaded PVDF or Polypropylene lens antenna for use in
chemical and sanitary environments where aggressive and
corrosive materials are used
• Graphical local user interface (LUI) makes operation simple
with plug-and-play setup using the intuitive Quick Start Wizard
• LUI displays echo profiles for diagnostic support
• 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
• 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 sup-
port. Startup is easy using the Quick Start wizard with a few
parameters required for basic operation.
SITRANS LR250’s unique design allows safe and simple pro-
gramming using the Intrinsically Safe handheld programmer
without having to open the instrument’s lid.
• Key Applications: liquid bulk storage tanks, process vessels
with agitators, vaporous liquids, corrosive and aggressive
materials.

Beam angle is the width of the
cone where the energy density
is half of the peak energy
density.
Note:
•
The peak energy density is
directly in front of and in line
with the antenna.
•
There is a signal transmitted
outside of the beam angle;
therefore false targets may be
detected.
