bypass pipes only form a complete antenna
system in conjunction with a
measuring pipe which can also
be bent. Pipe antennas are best
suited for products with extreme
product movements or products
with low dielectric constant figure.
The antenna can be with or with-
out horn. Antenna with horn
characterize by very good an-
tenna gain. A very good antenna
reliability can be achieved even
in case of products with very bad
reflection features.
The measuring pipe means a
conductor for radar signals. The
running period of the radar sig-
nals 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.
Product description
The antenna is the eye of the radar sensor.
Various antenna configurations are available
for different applications and process condi-
tions. Each system differs in the physical
features.
Horn antenna
Horn antennas focus the radar signals very
well. Manufactured of
1.4571 (stst) or Hastelloy
C22 they are very rugged
and physically as well as
chemically resistant. Horn
antennas are used for the
measurement in closed or
open vessels.
