VEGA VEGAVIB 66 - NAMUR - Manual (Page 12)

Warning:
The housing must not be used to screw in the instrument!
Applying tightening force on the housing can damage its
internal mechanical parts.
To screw in, use the hexagon above the thread.
4.2 Mounting information
Make sure that the max. permissible tensile load of the
suspension cable is not exceeded. The danger of this
happening exists particularly with very heavy solids and large
meas. lengths. The max. permissible load is stated under
"Technical data" in the "Supplement".
In silos with bulk solids, material cones can form which change
the switching point. Please keep this in mind when installing
the sensor in the vessel. We recommend selecting an
installation location where the sensor detects the average
value of the material cone.
The tuning fork must be mounted at a location that takes the
arrangement 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.
