SITRANS LR260
%Overview %Configuration
Mounting on a nozzle
Min. clearance:
10 mm (0.4")
SITRANS LR260 is a 2-wire 25 GHz pulse radar level transmitter
Installation
for continuous monitoring of solids in storage vessels including
5
extreme levels of dust and high temperatures, to a range of 30 m
min. 1 m (39")
(98.4 ft).
%Benefits
" Graphical local user interface (LUI) makes operation simple
emission
with plug-and-play setup using the intuitive Quick Start Wizard
cone
" 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 measure-
ment reliability and Auto False-Echo Suppression of fixed ob-
structions
" Programming using infrared Intrinsically Safe handheld pro-
grammer or SIMATIC PDM
beam angle:
2" horn = 15°
3" horn = 10°
%Application
4" horn = 8°
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 re-
quired for basic operation.
Positioning with Easy Aimer
SITRANS LR260 s unique design allows safe and simple pro-
gramming 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 bulk storage vessels, and other appli-
cations.

1. DC terminal shall be supplied from a source providing electrical isolation between the input and output, to meet the applicable safety requirements of IEC 61010-1.
3. Verwenden Sie geschirmtes Kabel mit verdrilltem Aderpaar (14 ... 22 AWG) für die HART Ausführung.
2. All field wiring must have insulation suitable for rated input voltages.
4. Eine getrennte Leitungsverlegung kann erforderlich sein, um Standardanforderungen an den Anschluss oder elektrische Richtlinien zu erfüllen.
3. Use shielded twisted pair cable (14 to 22 AWG) for HART version.
4. Separate cables and conduit may be required to conform to standard instrumentation wiring practices or electrical codes.
