Process Temperature And Pressure Rating - Emerson Rosemount 5408 Reference Manual

Specifications and Reference Data
November 2017
Scaled Variable - The scaled variable configuration allows
the user to convert a transmitter variable into an alternative
measurement, such as flow, mass, or calibrated level (e.g. 5
point verification).
User Defined Variable - Allows designating more than 200
variables in the device as output variable.
A.2.5 Process temperature and
pressure rating
The following figures give the maximum process
temperature (measured at the lower part of the flange, Tri
Clamp, or threaded connection) and pressure rating for
different antenna types.
Final rating may be lower depending on flange selection.
