Sizing
Contact an Emerson Process Management representative for
assistance. A Configuration Data Sheet is required prior to
order for application verification. To complete the
Configuration Data Sheet go to:

Annubar sensor surface finish
The front surface of the Annubar primary element is textured
for high Reynolds number applications (typically gas and
steam). The surface texture creates a more turbulent
boundary layer on the front surface of the sensor. The
increased turbulence produces a more predictable and
repeatable separation of flow at the edge of the sensor. The
appropriate surface finish will be determined for each
application by the Emerson Process Management sizing
program, Instrument Toolkit software.

Process temperature limits
Direct Mount Transmitter
 500 °F (260 °C)
 750 °F (398 °C) when used with a direct mount, high
temperature 5-valve manifold (Transmitter
Connection Platform code 6). Maximum temperature
limit for steam processes is 650 °F (343 °C).
Remote Mount Transmitter
 1250 °F (677 °C) – Alloy C-276 Sensor Material (For
superheated steam applications above 1000 °F
(538 °C), it is recommended that the Rosemount 585
with Alloy 800H sensor material is used.)
 850 °F (454 °C) – Stainless Steel Sensor Material
