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dierent
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,dierent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.
