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 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 instructions

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 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 fork detects an 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.
