1.3 Adjustment
Every measurement set-up is unique. For
that reason, every radar sensor needs some
basic information on the application and the
environment, e.g. which level means "empty“
and which level "full“. Beside this "empty and
full adjustment“, many other settings and
adjustments are possible with VEGAPULS
radar sensors.
The adjustment and parameter setting of
radar sensors is carried out with
- the PC
- the detachable adjustment module MINI-
COM
- the HART ® handheld
Temperature influence: Temperature error absolutely
zero (e.g. at 500°C 0.018 %)
Pressure influence: Error with pressure increase very
low (e.g. at 50 bar 1.44 %)

Continuous and accurate
Unaffected by temperature, pressure and
atmosphere content, VEGAPULS radar sen-
sors measure quickly and accurately the
levels of widely varying products.
VEGAPULS 50 sensors allow radar level
measurement in plants where they were it
was hitherto unthinkable because of high
costs.
1.2 Application features
Applications
• level measurement of any liquid, limited use
in solids
• measurement also in vacuum
• all slightly conductive materials and all
substances with a dielectric constant > 2.0
can be measured
• measuring range 0 … 20 m
Two-wire technology
• power supply and output signal on one
two-wire cable (Loop powered)
• 4 … 20 mA output signal
