Horn antenna
Horn antennas are best
suited for most applications.
They focus the radar signals
very well. Manufactured of
1.4571 (stst) they are very
rugged and physically as well
as chemically resistant. They
are suitable for pressures up
to 40 bar and for product
temperatures up to 150°C.

Pipe antennas on surge or
bypass pipes only form a
complete antenna system in
conjunction with a measuring
pipe which can also be bent.
Pipe antennas are especially
suitable for products with
heavy product movements or
products with low dielectric
constant figure.
The antenna can be with or
without horn. Versions with
horn characterize by very
good antenna gain. A very
good reliability can be
achieved even in case of
products with very bad
reflection features.
The meas. pipe means a
conductor for radar signals.
The running period of the
radar signals changes in the
pipe and depends on the
pipe diameter. The pipe inner
diameter must be
programmed in the
electronics so that the running
period can be compensated.
