Mounting: Horn Antennas Or Shielded Rod; Mounting: Waveguide Antenna - Siemens SITRANS LR 300 Instruction Manual

Mounting: Horn Antennas or Shielded Rod

The end of the horn, or the end of the shield section, should protrude a minimum of
10mm (0.5") to avoid interference with the nozzle.

Mounting: Waveguide Antenna

This option is recommended for products with
the related propagation factor.
Notes:
• You can connect a maximum of two waveguides together.
• This option is recommended only for clean liquids, and only on vessels without an
agitator, with no turbulence.
• Horizontal stress on this antenna must be avoided, otherwise mechanical support
may be required.
• Process temperature and pressure capabilities are dependent upon information on
the process device tag. The reference drawing listed on the tag is available upon
request.
