| 摘要 |
The invention relates to a measuring device for the measurement of properties of a material to be measured, in particular of the moisture content of agricultural harvested products such as hay, straw, or wilted silage, with a moisture sensor element ( 22, 49, 54, 62, 65 ) and at least one further sensor element for the detection of other material properties. In order to improve the measuring device it is proposed according to the invention that the further sensor element ( 23, 50, 58, 64, 66 ) is suitable for the measurement of the compression force exerted by the material to be measured on the moisture sensor element ( 22, 49, 54, 62, 65 ), or of a force corresponding to this compression force at another measuring point. In the measuring method according to the invention, the simultaneous measurement of the raw moisture value Qr and compression force F results in value pairs from which actual moisture values Q can be derived with a high degree of precision by means of a calibration surface ( 47 ), in a simple manner from the point of view of measurement technology.
