2.2 Description of the single components
Cable drum assembly
The cable drum helps to move the sensor up and down in the basin. It is mounted directly on the
axle of a synchronous motor, hidden behind the drum mounting plate.
The cable drum always moves with a very constant speed. Since the diameter of the cable roll in
the drum varies, the speed of the sensor varies. That is why the sensor moves slower during the
end of the sampling.
The cable and sensor are cleaned by a water spray in the flushing tube during return to the home
position.
