SITRANS LR200 with mA/HART
182
Operating Instructions, 05/2019, A5E32337676-AE
B.5
Process pressure/temperature derating curves
WARNING
Never attempt to loosen, remove or disassemble process connection or instrument housing
while vessel contents are under pressure.
CAUTION
Improper installation may result in loss of process pressure and/or release of process fluids
and/or gases.
Note
•
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 LR200 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, (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) Further markings (space permitting) indicate flange
configuration, size, pressure class, material, and material heat code.
•
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.
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.
