3.2 Principle of operation
The VEGAPULS 68 is a radar sensor for continuous measurement of
bulk solids also under arduous process conditions and large measur-
ing ranges. It the ideal solution for level measurement in high silos,
large bunkers, stone crushers and melting furnaces. With different
antenna versions and materials, this sensor is the optimum solution
for virtually all applications and processes.
The instrument is also suitable for applications in liquids.
Dependent on the application range, different versions are used:
•
Small silos and vessels, measurement of virtually all bulk solids:
Horn antenna
•
Large silos and vessels, measurement of bulk solids with low ε
r
value: Parabolic antenna
•
Liquids: Parabolic antenna
The instrument can be used with products with an ε
r
value ≥1.5. The
actually achievable value depends on the measuring conditions and
the antenna system.
