3.2 Principle of operation
The VEGAPULS 63 is a radar sensor for continuous level measure-
ment of aggressive liquids or with hygienic requirements. It is suitable
for applications in storage tanks, process vessels, dosing vessels and
reactors.
The standard electronics enables the use of instruments in products
with an ε
r
-Wert ≥1.8. The electronics version with increased sensitivity
enables the use of the instrument also in applications with very poor
reflective properties or products with an ε
r
value ≥1.5. The values that
can be actually reached depend on the measurement conditions, the
antenna system or the standpipe or bypass tube.
The antenna of the radar sensor emits short radar pulses with a
duration of approx. 1 ns. These pulses are reflected by the product
and received by the antenna as echoes. The transit time of the radar
pulses from emission to reception is proportional to the distance and
hence to the level. The determined level is converted into an appropri-
ate output signal and outputted as measured value.
The instrument is powered via an integrated accumulator. This allows
operation of the instrument independently of the mains or a control
system. To achieve a longer battery lifetime, the instrument is preset
to HART multidrop. This puts a load of only 4 mA current on the ac-
cumulator.
