xample:
I
n a vessel 20 m high, the installation position of the sensor is 1.4 m
from the vessel centre.
T
he necessary angle of inclination of 4° can be read out from this
chart.
P
roceed as follows to adjust the angle of inclination with the swivelling
holder:
1
L
oosen terminal screw of the swivelling holder with a fork spanner
SW
13
2
D
irect the sensor, check angle of inclination
Information:
T
he max. angle of inclination of the swivelling holder is approx. 15°
3
T
ighten the terminal screw, torque max. 20 Nm.
Information:
T
he hexagon screws must not be loosened.
M
ounting should not be too close to the inflowing material as the
microwave signal will be interferred. The optimum mounting position is
on the opposite of the filling. To avoid strong pollution, the distance to
the filter or dust extraction must be as big as possible.
