SITRANS LR200
SITRANS LR200 is a 2-wire loop-powered, continuous level measuring instrument that utilizes
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.
Communication is via HART1, and signals are processed using Sonic Intelligence®.

please refer to the process device tag.2
Ambient/Operating Temperature
WARNING: Changes or modifications not expressly approved by Siemens
could void the user’s authority to operate the equipment.
Notes:
• 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

user will be required to correct the interference at his own expense.
• SITRANS LR200 is to be used only in the manner outlined in this manual, otherwise
protection provided by the equipment may be impaired.
• This product is intended for use in industrial areas. Operation of this equipment in a
residential area may cause interference to several frequency based communications.

Recommendations
• Easy access for viewing the display and programming via the hand programmer.
• An environment suitable to the housing rating and materials of construction.
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.
WARNINGS:
• This product is designated as a Pressure Accessory per Directive 97 / 23 / EC,
and is not intended for use as a safety device.
• For pressure applications, it will be necessary to use PTFE paste or other
appropriate sealing compound, and to tighten the process connection beyond
hand-tight.
•Donot
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:
• This product can only function properly and safely if it is correctly transported,
stored, installed, set up, operated, and maintained.
• 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.
• 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.
• Please handle the device using the enclosure, not the antenna, to avoid damage.

/ type 4X / NEMA 6, IP67, IP68 locations.
• Read
Instructions specific to hazardous area installations on page 10.
Notes:
• For detailed wiring instructions, please refer to the full Instruction Manual.
• Use shielded, twisted pair cable: AWG 22 to 14 (0.34 mm2to 2.5 mm2).
• Separate cables and conduits2 may be required to conform to standard instrumentation
wiring practices, or electrical codes.
2. If cable is routed through conduit, use only approved suitable-size hubs for waterproof application.

Extension 100 mm (4")
Notes:
• Water or process fluids must not enter the
connecting threads: this could cause reflections at
the connection, which will appear as false echoes.
• Apply a small amount of PTFE paste to the antenna
threads before threading the antenna together, and
tighten slowly. Ensure that the rod sections mate
securely with no gaps. Do not apply too much PTFE
paste or the parts will not mate securely.
• Do not use wrenches or pliers. Hand tighten only
(except in pressure applications: see warning
above).

• Approved dust-tight and water-tight conduit seals are required for outdoor NEMA 4X /
type 4X / NEMA 6, IP67, IP68 locations.
• The maximum input voltage to the barrier must not exceed 250 V rms.
• Recommended intrinsically safe barriers are listed on page 9.
• Refer to
Instructions specific to hazardous area installations on page 10.
EU Equivalency (barrier selection)
Any zener diode safety barrier, certified by an EU approved certification body to [ EEx ia ] IIC,
its output voltage (Uo) not exceeding 30 V and its output current (Io) limited by load resistance
(Ro); such that Io= Uo/ Ro, does not exceed 120 mA.
IS Safety Barrier Selection
Selecting a suitable barrier or power supply requires knowledge about Intrinsic Safety and the
application. It is the responsibility of the installer to ensure that the intrinsically safe
installation complies with both the apparatus approval requirements and the relevant national
code of practice.
How to select a passive barrier for SITRANS LR200
1. Make sure that the barrier safety description is suitable for the LR200 Intrinsically Safe
(IS) input parameters.
2. Determine the maximum end-to-end resistance of the barrier (Re-e) from the data sheet.
3. Determine other loop resistance (Rloop): for example, sense resistance, displays, and/or
PLC inputs.
4. Calculate Rworking = Re-e + Rloop.
5. Determine any non-linear voltage drops due to the barrier (Vbarrier) from the barrier data
sheet (for example, voltage drops due to diodes).
6. Calculate Vworking = Vsupply – Vbarrier.
7. Using Vworking and Rworking, confirm that operation is within the shaded area of the
graph
Loop Voltage versus Loop Resistance on page 5 of Appendix A.

Notes:
• The following list is not complete: there are many safety barriers on the market, which
will work with the LR200.
• The barriers listed below have all been tested and are functionally compatible with the
LR 200.
• The barriers listed below are all HART compatible.
