FITTING THE SIEVE SENSOR
POSITION
The sieve sensor must be fitted so that it can measure the grain loss behind the
sieves over the whole width of the sieves. The best position for normal grain types
is 120 mm behind the rear edge of the sieves and 50 mm under the sieves
(measured from the centre of the tube).

The supplied brackets have three slits, when fitting measure from the middle slit.
This allows the sensor to be moved closer to the sieves when harvesting a crop
where not much air is blown under the sieves, i.e. oil seed rape. If the crop being
harvested needs a lot of air to be blown under the sieves the sensor can be moved
further away.
On some machines it might not be possible to fit the sensor in the recommended
position due to, e.g. the adjustment handle. In such cases it may be necessary to
fit the sensor higher or lower than the height given in the above. The centre of the
sensor must not be higher than the sieves or lower than 100 mm under the sieves.

Once the correct position has been found the brackets can welded or bolted to the
sieves. The point at which the brackets are attached must be stable so that the
sensor does not shake.
