SITRANS LR260
■ Overview
■ Configuration
Min. clearance:
10 (0.4)
Mounting on
a nozzle
4
Min. 1 000 (39)
Installation
SITRANS LR260 is a 2-wire 25 GHz pulse radar level transmitter
for continuous monitoring of solids and liquids in storage vessels
including extreme levels of dust and high temperatures, to a
range of 30 m (98.4 ft).
■ Benefits
Emission
cone
• 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
• 25 GHz high frequency allows for small horn antennas
mounted easily in nozzles
• Communication using HART or PROFIBUS PA
• Process Intelligence signal processing for improved
measurement reliability and Auto False-Echo Suppression of
fixed obstructions
• Programming using infrared Intrinsically Safe handheld
programmer or SIMATIC PDM
Beam angle:
2" horn = 15°
3" horn = 10°
4" horn = 8°
■ Application
SITRANS LR260 includes a graphical local user interface (LUI)
that improves setup and operation using 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.
Positioning with
Easy Aimer
SITRANS LR260’s unique design allows safe and simple programming using the Intrinsically Safe handheld programmer
without having to open the instrument’s lid.
SITRANS LR260 measures virtually any solids material to a
range of 30 m (98.4 ft).
• Key Applications: cement powder, plastic powder/pellets,
grain, flour, coal, solids and liquids bulk storage vessels, and
other applications
