1 Product description
VEGAPULS series 40 sensors are a newly
developed generation of extremely compact
radar sensors for high resolution and accu-
racy. They are characterised by very good
focussing features for applications in narrow
spaces. With very modest space require-
ments, they were developed for measuring
distances of 0 … 10 m/20 m and are the right
choice for standard applications such as
storage vessels, reservoirs and buffer tanks
as well as process tanks.
Due to small housing dimensions and proc-
ess fittings, the compact sensors are an
obstrusive, and most of all, very reasonable
solution for your level measurement applica-
tions. With the integrated display they enable
high precision level measurements and can
be used for applications in which the advan-
tages of non-contact measurement could
never before be realized.
VEGAPULS 40 radar sensors are perfectly
suited to two-wire technology. The supply
voltage and the output signal are transmitted
via one two-wire cable. As output or measur-
ing signal, the instruments produce an ana-
logue 4 … 20 mA output signal.
1.1 Function
Radio detecting and ranging: Radar.
VEGAPULS radar sensors are used for non-
contact, continuous distance measurement.
The measured distance corresponds to a
filling height and is outputted as level.
Measuring principle:
emission – reflection – reception
Tiny 24 GHz radar signals are emitted from
the antenna of the radar sensor as short
pulses. The radar impulses reflected by the
sensor environment and the product are
received by the antenna as radar echoes.
The running period of the radar impulses
from emission to reception is proportional to
the distance and hence to the level.
