Installation
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.
• Handle the device using the enclosure, not the antenna or the device tag, to avoid
damage.
Notes:
• The Process Device Tag shall remain with the process pressure boundary assembly
the event the device package is replaced, the Process Device Tag shall be transferred to
the replacement unit.
• SITRANS LR200 units are hydrostatically tested, meeting or exceeding the requirements
of the ASME Boiler and Pressure Vessel Code and the European Pressure Equipment
Directive.
Pressure Application
WARNINGS:
• Never attempt to loosen, remove, or disassemble process connection or instru-
ment housing while vessel contents are under pressure.
• Improper installation may result in loss of process pressure.
Pressure Equipment Directive, PED, 97/23/EC
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).

Nozzle design

Notes:
• For nozzles 100 mm (4") in length or shorter use the 100 mm (4") shield.
• For nozzles 250 mm (10") in length or shorter use the 250 mm (10") shield.
• For horn and waveguide versions see the full manual which can be downloaded from
www.siemens.com/LR200.

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.
