Installation notes
●
Refer to device nameplate for approval information.
●
The process device tag shall remain with the 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
instrument package is replaced, the process device tag shall be transferred to the
replacement unit.
●
SITRANS Probe LR units are hydrostatically tested, meeting or exceeding the
requirements of the ASME Boiler and Pressure Vessel Code and the European Pressure
Equipment Directive.
●
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.
Recommendations
●
Ensure ambient temperature is within –40 to 80 °C (–40 to 176 °F).
●
Provide easy access for viewing the display and programming via the handheld
programmer.
●
Ensure the environment is suitable to the housing rating and materials of construction.
