Engineered solutions

When standard model codes are not sufficient to fulfil 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 R-labeled numeric option code that should be added at

the end of the standard model string. See example model string below.

Example Model String: 3301-H-A-1-S-1-V-5A-E-33-00-RC-I5-M1W3C1-R1234

A.3.4 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 3300 Series transmitters.

The probe length to use for a Rosemount 9901 chamber can be calculated with this formula:

Side-and-side dimension:

Probe length = centre-to-centre dimension + 19 in. (48 cm)

Side-and-bottom dimension:

Probe length = centre-to-centre dimension + 4 in. (10 cm)

Use a centering disc the same diameter as the chamber if the probe length > 3.3 ft. (1 m). See

Probe type in chamber considerations and Centering discs on page 139 for which probe and

disc to use.
