VEGAPULS 51 V … 54 V 9
VEGAPULS series 50 sensors are a new
developed generation of very compact, small
radar sensors. With only very narrow space
requirements they are developed for short
meas. distances (0 … 20 m) and for
standard applications such as storage tanks
and buffer tanks.
Due to the small housing dimensions and
process connections, the compact sensors
monitor your levels very price favourably.
With the integral indication and the many
features of the "big brothers" of VEGAPULS
series 64 and especially of VEGAPULS
series 81, they open the advantages of a
radar level measurement for applications in
which the special adavantages of radar were
not possible, due to price reasons.
VEGAPULS 50 radar sensors dominate the
two-wire technology perfectly. They are the
first radar sensors transmitting supply
voltage and output signal via one two-wire
line. As output or meas. signal they provide a
digital output signal.
2.1 Type survey
The antenna is the eye of the radar sensor.
Four antenna systems are available for diffe-
rent applications and process requirements.
Each system differs in the physical features.
Rod antenna
Rod antennas with high
chemical resistance require
smallest flange dimensions
(DN 50). The antenna rod and
the wetted flange parts are
made of PTFE, PP or PPS so
that the rod antenna can be
easily cleaned and is
insensitive to condensation.
The rod antenna is suitable for
pressures up to 16 bar and
temperatures up to 150°C.
