SITRANS LR260

■

Overview

SITRANS LR260 is a 2-wire, 25 GHz pulse radar level transmitter

for continuous monitoring of solids and liquids in storage ves-

sels, including extreme levels of dust and high temperatures, to

a range of 30 m (98.4 ft).

■

Benefits

• 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

■

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 re-

quired for basic operation.

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.

• Key Applications: cement powder, plastic pellets, aggregates,

coal, solids and liquids bulk storage vessels.
