Installation
Dimensions: Horn
∗
A purging system is an option available for this antenna type. This provides an inlet on
the flange where cooling air or cleaning fluid may be supplied. The air or liquid passes
through the flange and exits the inside of the horn to clean the antenna system.
Notes:
• Process temperature and pressure capabilities are dependent upon information on
the process device tag. Reference drawing listed on the tag is available upon
request.
• The Process Device Tag shall remain with the process pressure boundary assembly.
In the event the instrument package is replaced, the Process Device Tag shall be
transferred to the replacement unit.
WARNING: The user is responsible for the selection of bolting and
gasket materials which will fall within the limits of the flange and
its intended use and which are suitable for the service conditions.

• Signal amplitude increases with
horn diameter, so use the largest
practical size.
• Optional waveguide extensions
and/or purging system * can be
installed between the flange and
