4 Mounting
VEGAVIB 61 • Two-wire 8/16 mA
29268-EN-170315
In abrasive solids, mounting according to illustration "b" has proven.
A spout forms in the concave protective sheet preventing wear of the
protective sheet.
In silos for bulk solids, material cones can form and change the
switching point. Please keep this in mind when installing the sensor
in the vessel. We recommend selecting an installation location where
the vibrating rod detects an average value of the material cone.
The vibrating rod must be mounted in a way that takes the arrange-
ment of the filling and emptying apertures into account.
To compensate measurement errors caused by the material cone in
cylindrical vessels, the sensor must be mounted at a distance of d/6
from the vessel wall.
