Product description
Pipe antennas
The pipe antennas on surge
or bypass tubes only form a
complete antenna system in
conjunction with a measuring
tube (which can also be
curved). The measuring tube
acts as a conductor for
radar signals. The running
period of the radar signals
changes in the tube and is
dependent on tube diameter.
The tube inner diameter must
be programmed in the sen-
sor so that it can take the
altered running time into
account and deliver precise
level signals. Pipe antennas
are especially suitable for
processes with intense
product movements or prod-
ucts with low dielectric con-
stant.
The antennas are character-
ised by very high gain. High
reliability can be achieved
even with products with very
poor reflective features.
