2.3 Requirements for special applications
Due to the large number of possible applications, each detail of the described device versions
for each possible scenario during commissioning, operation, maintenance or operation in
systems cannot be considered in the instructions. If you need additional information not covered
by these instructions, contact your local Siemens office or company representative.
We highly recommend that you contact your Siemens representative or our application
department before you operate the device under special ambient conditions as can be
encountered in nuclear power plants or when the device is used for research and
development purposes.
Persons who install, connect, commission, operate, and service the device in a hazardous area
must have the following specific qualifications:
● They are authorized, trained or instructed in operating and maintaining devices and systems
according to the safety regulations for electrical circuits, high pressures, aggressive, and
hazardous media.
● They are authorized, trained, or instructed in carrying out work on electrical circuits for
hazardous systems.
● They are trained or instructed in maintenance and use of appropriate safety equipment
according to the pertinent safety regulations.
If the device has already been operated in non-intrinsically safe circuits or the electrical
specifications have not been observed, the safety of the device is no longer ensured for use
in hazardous areas. There is a danger of explosion.
• Connect the device with type of protection "Intrinsic safety" solely to an intrinsically safe
circuit.
• Observe the specifications for the electrical data on the certificate.

SITRANS LR250 overview
WARNING
Loss of protection
Danger to personnel, system and environment can result from improper use of the device.
• SITRANS LR250 is to be used only in the manner outlined in this manual, otherwise
protection provided by the device may be impaired.
SITRANS LR250 is a 2-wire 25 GHz pulse radar level transmitter for continuous monitoring of
liquids and slurries in storage vessels including high pressure and high temperature, to a range
of 20 meters (66 feet). It is ideal for small vessels, material such as chemicals, food, beverages,
solvents (including those of corrosive or aggressive nature), and low dielectric media.
The device consists of an electronic circuit coupled to an antenna and either a threaded or
flange type process connection.
This device supports Foundation Fieldbus (FF) communication protocol. Signals are processed
using Process Intelligence which has been field proven in over 1,000,000 applications worldwide
(ultrasonic and radar). This device can be configured as an FF (H1) Link Master.
This device is very easy to install and configure via a graphical local user interface (LUI). You
can modify the built in parameters either locally via the Siemens infrared handheld programmer,
or from a remote location using one of the following options:
● FF host system
● AMS Device Manager
● liquids and slurries
● bulk storage vessels
● simple process vessels
● corrosive and aggressive
● hygienic/sanitary
For further details see Approvals (Page 219).
SITRANS LR250 is available with approvals for General purpose, sanitary or hygienic and for
hazardous areas. In all cases, check the nameplate on your device, and confirm the approval
rating.
A wide range of process connections and antenna options are available to suit virtually any
vessel configuration.

Material compatibility
WARNING
Unsuitable connecting parts
WARNING
Exceeded maximum ambient or process media temperature
WARNING
Open cable inlet or incorrect cable gland
Siemens can provide you with support concerning selection of sensor components wetted by
process media. However, you are responsible for the selection of components. Siemens
accepts no liability for faults or failures resulting from incompatible materials.
Danger of injury or poisoning.
In case of improper mounting hot, toxic and corrosive process media could be released at
the connections.
• Ensure that connecting parts (such as flange gaskets and bolts) are suitable for
connection and process media.
Danger of explosion in hazardous areas.
Device damage.
• Make sure that the maximum permissible ambient and process media temperatures of
the device are not exceeded.
Danger of explosion in hazardous areas.
• Close the cable inlets for the electrical connections. Only use cable glands or plugs
which are approved for the relevant type of protection.
Danger of explosion in hazardous areas as result of open cable inlet or incorrect conduit
system.
• In the case of a conduit system, mount a spark barrier at a defined distance from the
device input. Observe national regulations and the requirements stated in the relevant
approvals.
Danger to personnel, system and environment will result from improper disassembly.
• Never attempt to loosen, remove, or disassemble process connection while vessel
contents are under pressure.
Danger to personnel, system and environment can result from improper installation.
• Improper installation may result in loss of process pressure.
Danger of injury or poisoning.
The maximum permissible operating pressure depends on the device version. The device
can be damaged if the operating pressure is exceeded. Hot, toxic and corrosive process
media could be released.
• Make sure that the device is suitable for the maximum permissible operating pressure of
your system.

Note
4.1.1.1
Pressure Equipment Directive, PED, 97/23/EC
4.1 Basic safety information
• The process connection tag shall remain with the process pressure boundary assembly.
(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). In the
event the device package is replaced, the process connection tag shall be transferred to
the replacement unit.
• SITRANS LR250 units are hydrostatically tested, meeting or exceeding the requirement
of the ASME Boiler and Pressure Vessel Code and the European Pressure Equipment
Directive.
• The serial numbers stamped in each process connection body, (flange, threaded, or
sanitary), provide a unique identification number indicating date of manufacture.
Example: MMDDYY – XXX (where MM = month, DD = day, YY = year, and XXX=
sequential unit produced)
Siemens Level Transmitters with flanged, threaded, or sanitary clamp type process mounts have
no pressure-bearing housing of their own and, therefore, do not come under the Pressure
Equipment Directive as pressure or safety accessories (see EU Commission Guideline 1/8 and
1/20).
Danger to personnel, system and environment can result from unsuitable environment.
• Provide an environment suitable to the housing rating and materials of construction.
Device damage.
The device can overheat or materials become brittle due to UV exposure.
• Protect the device from direct sunlight.
• Make sure that the maximum permissible ambient temperature is not exceeded. Refer
to the information in Chapter "Technical data".

details listed on a tag.
• Correct location is key to a successful application.
• Avoid reflective interference from vessel walls and obstructions by following guidelines in
this chapter.
The device can be damaged, destroyed, or its functionality impaired through improper
mounting.
• Before installing ensure there is no visible damage to the device.
• Make sure that process connectors are clean, and suitable gaskets and glands are
used.
• Mount the device using suitable tools. Refer to the information in Installation instructions
(Page 34) for installation torque requirements.
• On devices with a removable head, there is no limit to the number of times a device can
be rotated without damage.
• When mounting, orient the front or back of the device towards the closest vessel wall or
obstruction.
• Do not rotate the enclosure after programming and vessel calibration, otherwise an error
may occur, caused by a polarity shift of the transmit pulse.

● The maximum nozzle length for the FEA is 500 mm (19.68") when the nozzle diameter is
DN150 (6"). Only shorter lengths are recommended for smaller diameters.
● When installing the SITRANS LR250 with hygienic process connection, it is good hygienic
practice to install the antenna in a nozzle that has a maximum length/diameter ratio of 1:1.
For example, 2" (DN50) diameter nozzle should be no longer than 2" (50 mm).
● When removing any sanitary/hygienic clamp version of the HEA to clean the lens, ensure it is
re-installed in the exact position it was removed from, to avoid re-commissioning the device.
