3.2Principle of operation
VEGAPULS 68 is a radar sensor in K-band technology for
continuous level measurement of solids.
Aversion of VEGAPULS 68 is available for each area of
application:
lThe version with horn antenna is particularly suitable for
measurement of virtually all bulk solids in small silos and
vessels.
lThe version with parabolic antenna is particularly suitable
for large silos and vessels with up to 70 m(76 yd)
measuring distance and for measurement of solids with low
dielectric constant.
VEGAPULS 68 is also suitable for applications in liquids.
The antenna of the radar sensor emits short radar pulses with
a duration of approx.1ns.These pulses are reflected by the
product and received by the antenna as echoes.The running
time of the radar pulses from emission to reception is

4.1General instructions
Select an installation position you can easily reach for
mounting and connecting as well as later retrofitting of an
indicating and adjustment module.The housing can be rotated
by 330°without the use of any tools.You can also install the
indicating and adjustment module in four different positions
(each displaced by 90°).
Warning:
The housing of the threaded versions must not be used to
screw the instrument in!Applying tightening force on the
housing can damage its rotational mechanical parts.
Use the recommended cables (see chapter "Connecting to
power supply")and tighten the cable gland.
You can give your VEGAPULS 68 additional protection against
moisture penetration by leading the connection cable down-
ward in front of the cable entry.Rain and condensation water
can thus drain off.This applies mainly to mounting outdoors,in
areas where moisture is expected (e.g.by cleaning processes)
or on cooled or heated vessels.

4.4Mounting instructions
The illustrations in the mounting instructions show a VEGA-
PULS 68 with horn antenna.The mounting instructions also
apply to VEGAPULS 68 with parabolic antenna.
Mount the sensor at 200 mm (7.874 in)away from the vessel
wall.
12
Fig.6:Installation position
1Reference plane
If this distance cannot be maintained,a false echo storage
should be carried out during setup.This applies particularly if
buildup on the vessel wall is expected.In such case,we
recommend repeating the false echo storage later on with
existing buildup.
To detect nearly the complete vessel volume the sensor
should be directed in such a way that the measuring beam
reaches the lowest level in the vessel.In a cylindrical silo with
conical outlet,it is the easiest way to mount in the center of the
silo.
