VEGA VEGAWAVE 62 - NAMUR - Manual (Page 11)

The max. permissible pressure is specified in chapter "Technical data"
or on the type label of the sensor.
The vibrating level switch is a measuring instrument and must be
treated accordingly. Bending the vibrating element will destroy the
instrument.
Warning:
The housing must not be used to screw the instrument in! Applying
tightening force can damage internal parts of the housing.
Use the hexagon above the thread for screwing in.
4 .2 Instructions for installation
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 in chapter "Technical data".
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 in a way 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.
