Model and antenna guide
Rosemount 5402 Rosemount 5401
This table gives guidelines on which
model and antenna to select, depending
on application.
G = Good
AD = Application Dependent (contact
your local Emerson Automation Solution
representative)
NR = Not Recommended
Cone (preferred) Process seal Parabolic Cone (preferred) Rod
Best choice for a
broad range of
applications, free
propagation and
pipe installations.
Ideal for small tanks
and corrosive
applications. Good for
heavy antenna
condensation/build-up.
Only for solids
applications. Good
for long ranges.
Suitable for some
extreme process
conditions.
Suitable for small
process
connections, and
corrosive
environment.
