Figure A-20. Rosemount 9901 Chamber Insallation
For additional information, see the Rosemount 9901 Chamber for Process Level Instrumentation
Product Data Sheet (document number 00813-0100-4601).
Existing chamber
A Rosemount 3300 Series Transmitter is the perfect replacement in an existing displacer
chamber.
Proprietary flanges are offered, enabling use of existing chambers to make installation easy.
Considerations when changing to the Rosemount 3300 Series:
The Rosemount 3300 Series flange choice and probe length must be correctly matched
to the chamber. Both standard ANSI and EN (DIN), as well as proprietary chamber
flanges, are available. See “Proprietary flanges” on page 151 to identify the proprietary
flanges.
See Probe type in chamber considerations and Centering discs on page 139 for which
probe and disc to use. See Table A-8 on page 140 for guidelines on the required probe
length.
