Application Examples
The application example used in this manual illustrates a typical installation using
SITRANS LR 200 (PROFIBUS PA). Because there is often a range of ways to approach an
application, other configurations may also apply. If the example does not apply to your
application, check the applicable parameter reference for the available options.
A standard level application is found on page 23: see also
Appendix E: Special
Applications
on page 59.

Abbreviations and Identifications
Note:This equipment has been tested and found to comply with the limits for a
Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to
provide reasonable protection against harmful interference when the equipment is
operated in a commercial environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference,
in which case the user will be required to correct the interference at his own expense.

SITRANS LR 200
SITRANS LR 200
SITRANS LR 200 (PROFIBUS PA) is a 2-wire loop-powered, continuous level measuring
instrument that uses advanced pulse radar technology at 5.8 GHz (6.3 GHz in North
America). The instrument consists of an electronic component coupled to the antenna
and process connection. It is very easy to install and set up, using either the infrared
hand-held programmer locally, or using SIMATIC®PDM from a remote location.
Communication is via PROFIBUS PA. Signals are processed using Sonic Intelligence®
which has been field-proven in over 500,000 applications worldwide (ultrasonic and
radar). This device supports acyclic communications from both a PROFIBUS Class I and
Class II master.
SITRANS LR 200 is available in two versions
• General Purpose (non-hazardous)
• Intrinsically Safe (with suitable barrier)
A wide range of process connections and antenna options is available to suit virtually
any vessel configuration.
Applications
shield length: 100 mm (4"):
use for nozzles of 100 mm (4")
or less in length
shield length 250 mm (10"):
use for long nozzles of 250 mm (10")

Mounting location
Recommendations:
• Ensure the ambient temperature is within –40 to 80 oC (–40 to 176 oF)1.
• Ensure the environment is suitable to the housing rating and materials of
construction.2
• Provide easy access for viewing the display and programming via the hand
programmer.
Precautions:
• Avoid proximity to high voltage or current wiring, high voltage or current contacts,
and to variable frequency motor speed controllers.
• Avoid interference to the emission cone from obstructions or from the fill path.
• Avoid central locations on vessels.3
WARNINGS:
• SITRANS LR 200 is to be used only in the manner outlined in this
manual, otherwise protection provided by the equipment may be
impaired.
• Installation shall only be performed by qualified personnel and in
accordance with local governing regulations.
• Pleasehandle thedeviceusingtheenclosure,nottheantenna,toavoid
damage.
Note:Please refer to product label for approval information.

Installation
Keep the emission cone free of interference:
• Make allowance for the emission cone spreading: allow a minimum of 300 mm (1 ft)
for every 3 m (10 ft) of vessel height.
• Locate the antenna away from the side wall, to avoid interference from indirect
echoes.
• Avoid interference (from objects such as ladders or pipes, or from the fill path)
which can cause false reflections1.
WARNING: For vessels with conicalor parabolic tops, avoid
mountingtheinstrumentat the centre. (Theconcavity of the top can
focus echoes into the centre, giving false readings.)
Note:Under certain circumstances, it may be acceptable to mount SITRANS LR 200 at
the centre of a flat-topped tank: please discuss this with your Siemens Milltronics
Representative.

Installation
Location on a nozzle, or on a manhole cover
On a nozzle, the end of the shield section should protrude a minimum of 10 mm (0.4”) to
avoid interference.
A manhole cover is typically a covered nozzle with a diameter 610 mm (24”) or greater. To
provide optimum signal conditions on a manhole cover, locate the antenna off-center,
typically 100 mm (4") from the side.
Mounting Instructions
1. Before inserting SITRANS LR 200 into its mounting connection, check to ensure the
threads are matching, to avoid damaging them.
2. Simply screw the LR 200 into the process connection, and hand tighten. For pressure
applications, it will be necessary to use PTFE tape (or other appropriate thread
sealing compound) and tighten the process connection beyond hand tight.
The maximum torque is 40 N-m (30 ft.lbs).
3. If you want to rotate the enclosure, use a 2 mm Allen key to loosen the set-screws
that secure the locking ring.
4. Once the enclosure is in a suitable position, tighten the set-screws.
Notes:
• Use the 100 mm (4") shield on nozzles that are 100 mm (4") in length, or shorter.
• Use the 250 mm (10") shield on nozzles that are 250 mm (10") in length, or shorter.
Note:See also Appendix E: Special Applications on page 59.
Note:Do not rotate the enclosure after programming and vessel calibration, otherwise
an error may occur, caused by a polarity shift of the transmit pulse.
