4. Measuring condition: Homogeneous filling
The product must be homogeneous. If the product is not mixed
or asymmetrical in the chute, then the moisture reading is not
representative and the sampling (e.g. for calibration) can be in-
correct, see Figure 4-17.
Figure 4-17:
Two different
products (e.g.
through different
moistures) cannot
be mixed and filled
asymmetrically.

4.4.3 Installation
The measuring chute and the horn antennas with their holders
are usually mounted on the assembly plate by Berthold Technol-
ogies, see
chapter 8.6 Installation Proposal Measuring Chute .
The measuring chute with assembly plate is installed into the
conveyor flow at a suitable location. There must be no chute ta-
pering and fixtures before and after the measuring chute on a
length of at least 400 mm. In individual cases, the inlet and outlet
pipes can be shortened, the design is done in the project planning
stage.
Assemble the components in accordance with the dimensional
drawing in
chapter 8.6 Installation Proposal Measuring Chute . All
mounting holes for brackets and measuring chute are provided
on the assembly plate so that the measuring path is perfectly
aligned.
Protect the antennas against dust and dirt. Install the measuring
chute to your conveyor system such that you are able to reach
all parts of the measuring chute easily. Provide a stable and vi-
bration-free mounting of the assembly plate. A material sampling
location should be foreseen in the vicinity of the measuring chute
for the necessary calibration.
If a PT100 is used, it should be oriented towards the H-field, see
Figure 3-14 in
chapter 3.7.4 Measuring Chute .
The terminals of the horn antennas should preferably point down-
wards, so that they are better protected.
Important: Bulk goods have to be conveyed evenly through the
measuring chute and it has to be ensured that the chute is filled
completely for the measurement.
