Claim 19:
20. A sensor arrangement for detecting a density of harvested crops deposited as silage in a silo, comprising:
a source of a pressurized gaseous medium,
an opening connected by a line to the source and which is movable along a surface of the silage, the gaseous medium being guided out of the opening from the source into the silage,
a sensor for detecting a property of the medium flowing through the line,
an evaluation device connected to the sensor and configured to provide an output signal including information based on the signal of the sensor regarding the density of the silage, and
a valve positioned between the source and the opening, the pressure of the medium at the opening being adjustably controlled to a predetermined pressure by the valve,
wherein, the evaluation device determines the output signal on the basis of a volumetric flow rate detected by the sensor.
