A.3.3 Engineered solutions
When standard model codes are not sufficient to fulfill requirements, please consult the factory
to explore possible Engineered Solutions. This is typically, but not exclusively, related to the
choice of wetted materials or the design of a process connection. These Engineered Solutions
are part of the expanded offerings and may be subject to additional delivery lead time. For
ordering, factory will supply a special P-labeled numeric option code that should be added at
the end of the standard model string. See example model string below.
Example Model String:
3308A-S-X-2-D1-I5-S-1-V-2-NN-N-5A-E-030-00-WA3-WK1-M5-W3-P1234
A.3.4 Chamber/pipe installations
General chamber considerations
The recommended minimum chamber diameter is 4 in. (100 mm) for Single Flexible probe and
3 in. (75 mm) for the Single Rigid probe. The probe should be centered to prevent it touching
the sides of the well.
PTFE covered probes are not recommended for chamber/pipe installations.
Rosemount 9901 Chamber
Rosemount 9901 allows external mounting of process level instrumentation. It supports a
variety of process connections, and optional drain and vent connections. The Rosemount 9901
chamber is designed to the ASME B31.3 standard, and is Pressure Equipment Directive (PED)
compliant. Use option code XC to order together with the 3308 Series Transmitter.
