Product description
The signal reflection increases with the con-
ductivity or with the dielectric constant of the
medium. Hence virtually all mediums can be
measured.
Due to standard flanges from DN 50 to
DN 250, ANSI 2“ to ANSI 10“ the sensor
antenna systems are adapted to the various
measured products and process environ-
ments. High-quality materials withstand also
extremely chemical and physical conditions.
The sensors deliver reliable, precise and
longterm stable, reproducible analogue or
digital level signals.
Continuous and reliable
Unaffected by temperature, pressure and
atmosphere type, VEGAPULS radar sensors
detect quickly and precise levels of different
mediums.
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
0,8 %)

VEGAPULS 56 enable level measurements
where radar sensors could not be used
before.
