SITRANS LR260
SITRANS LR260 is a 2-wire 25 GHz pulse radar level transmitter for continuous monitoring of
solids in storage vessels including extreme levels of dust and high temperatures, to a range of
30 m (98.4 ft).
The instrument consists of an electronic component coupled to a horn antenna with an
integral Easy Aimer and flange for quick and easy positioning. A dust cover or air purging are
available as options.
WARNING: relates to a caution symbol on the product, and means that failure to
observe the necessary precautions can result in death, serious injury, and/or
considerable material damage.

Pressure Application
Installation1
Installation guidelines
• Provide easy access for viewing the display and programming via the hand programmer.
• Provide an environment suitable to the housing rating and materials of construction.
• Provide a sunshield if the device will be mounted in direct sunlight.
Nozzle design
• The end of the horn must protrude a minimum of
10 mm (0.4”) to avoid false echoes being reflected
from the nozzle.
• Optional antenna extension: 100 mm (3.93"),
200 mm (70.9"), 500 mm (19.69"), 1000 mm (39.4")2
WARNINGS:
• This product is designated as a Pressure Accessory per Directive 97 / 23 / EC, and
is not intended for use as a safety device.
• Do not attempt to loosen, remove, or disassemble process connection or
instrument housing while vessel contents are under pressure.
• Improper installation may result in loss of process pressure.
WARNINGS:
• Installation shall only be performed by qualified personnel and in
accordance with local governing regulations.
• Materials of construction are chosen based on their chemical compatibility (or
inertness) for general purposes. For exposure to specific environments, check
with chemical compatibility charts before installing.
Notes:
• For European Union and member countries, installation must be according to ETSI EN
302372.
• The Process Device Tag shall remain with the process pressure boundary assembly1. In
the event the instrument package is replaced, the Process Device Tag shall be transferred
to the replacement unit.
• SITRANS LR260 units are hydrostatically tested, meeting or exceeding the requirements
of the ASME Boiler and Pressure Vessel Code and the European Pressure Equipment
Directive.
1. The process pressure boundary assembly comprises the components that act as a barrier against
pressure loss from the process vessel: that is, the combination of process connection body and
emitter, but normally excluding the electrical enclosure.
2. Extensions are not recommended for applications where there may be excessive visible vibration.
Please consult factory for more information.

Nozzle location
• Keep emission cone free of
interference from ladders, pipes,
I-beams or filling streams.
• Avoid central locations on tall,
narrow vessels.
• Align the antenna so that the
radar cone is perpendicular to the
surface of the monitored material,
if possible.

Note: Beam angle depends on horn
size.
WARNING: The user is responsible for the selection of bolting and gasket materials
which will fall within the limits of the flange and its intended use, and which are
suitable for the service conditions.
WARNINGS:
The DC input terminals shall be supplied from a source providing electrical
isolation between the input and output, meeting the applicable safety
requirements of IEC 61010-1.
All field wiring must have insulation suitable for rated voltages.

Connecting SITRANS LR260
1. Use a 2 mm Allen key to loosen the lid-lock set screw then using a screwdriver for
leverage if necessary, unscrew the cover.
2. Strip the cable jacket for approximately 70 mm (2.75") from the end of the cable, and
thread the wires through the gland1.
3. Connect the wires to the terminal as shown (SITRANS LR260 is not polarity sensitive)
4. Ground the device according to local regulations.
5. Tighten the gland to form a good seal.
6. Close the lid and secure the locking ring before programming and calibration..
WARNINGS:
• Check the device nameplate and process device tag, to verify the approval rating.
• Use appropriate conduit seals to maintain IP or NEMA rating.
•Read Wiring setup for hazardous area installations on page 7.
Note:
• For detailed wiring instructions refer to the full Instruction Manual.
• Use twisted pair cable: AWG 22 to 14 (0.34 mm² to 2.5 mm²).
• Separate cables and conduits may be required to conform to standard instrumentation
wiring practices, or electrical codes.
1. If cable is routed through conduit, use only approved suitable-size hubs for waterproof applications.
Notes:
• PROFIBUS PA must be terminated at both extreme ends of the cable for it to work
properly.
• Please refer to the PROFIBUS PA User and Installation Guidelines (order number 2.092),
available from www.profibus.com, for information on installing PROFIBUS devices.
