WARNINGS:
Installation shall only be performed by qualified personnel and in
accordance with local governing regulations.
SITRANS LR250 is to be used only in the manner outlined in this manual,
otherwise protection provided by the device may be impaired.
Handle the device using the enclosure not the device tag, to avoid
damage.
Never attempt to loosen, remove, or disassemble process connection
or instrument housing while vessel contents are under pressure.
This product is designated as a Pressure Accessory per Directive
97/23/EC and is not
intended for use as a safety device.
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.
Improper installation may result in loss of process pressure.
Notes:
For European Union and member countries, installation must be according to ETSI
EN 302372.
Refer to the device nameplate for approval information.
The Process Device Tag shall remain with the process pressure boundary
assembly
1
. In the event the instrument package is replaced, the Process Device Tag
shall be transferred to the replacement unit.
SITRANS LR250 units are hydrostatically tested, meeting or exceeding the
requirements of the ASME Boiler and Pressure Vessel Code and the European
Pressure Equipment Directive.
The serial numbers stamped in each process connection body provide a unique
identification number indicating date of manufacture.
Example: MMDDYY – XXX (where MM = month, DD = day, YY = year, and
XXX= sequential unit produced)
Further markings (space permitting) indicate flange configuration, size, pressure
class, material, and material heat code.
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.
