Abstract
In a device for and a method of calibrating the measurement of a product stream in agricultural machines, a calibrating unit is arranged after a measuring unit, a definite quantity of a product stream is weighed in the calibrating unit and the weight value is determined in an evaluating electronic unit which compares the weight value with a value determined by the measuring unit and determines a correction factor from the comparison of both values.

A device for calibrating the measurements of a product stream on an agricultural machine, comprising measuring means for measuring a product stream and producing a first measured weight value;
- calibrating means;
- deviating means arranged so that the whole product stream after passing said measuring means is directed by said deviating means to said calibrating means and is weighed in said calibrating means to produce a second weight value;
- and evaluating means for comparing said first measured weight value with said second weighed weight value.
A device for calibrating the measurements of a product stream on an agricultural machine, comprising measuring means for measuring a product stream;
- calibrating means;
- and deviating means arranged so that the product stream after passing said measuring means is directed by said deviating means to said calibrating means and is weighed in said calibrating means;
- and transporting means for transporting the product stream and including a plurality of transporting elements, said deviating means being formed so that a deviation of the product stream is formed in dependence on positions of individual ones of said transporting elements.
A device for calibrating the measurements of a product stream on an agricultural machine, comprising measuring means for measuring a product stream;
- calibrating means;
- and deviating means arranged so that the product stream after passing said measuring means is directed by said deviating means to said calibrating means and is weighed in said calibrating means;
- and a transporting means for transporting the product stream, said deviating means being formed so that a deviation of the product stream is performed in dependence on a transporting speed of said transporting means.
A method of calibrating the measurements of a product stream on an agricultural machine, comprising the steps of measuring a product stream in measuring means to determined a first measured weight value;
- after passing the measuring means, deviating the whole product stream by deviating means;
- and receiving the deviated product stream by calibrating means and weighing the product stream in the calibrating means to determine a second weighed weight value;
- and comparing said first measured value with said second weighed value.
A method of calibrating the measurements of a product stream on an agricultural machine, comprising the steps of measuring a product stream in measuring means;
- after passing the measuring means, deviating the product stream by deviating means;
- and receiving the deviated product stream by calibrating means and weighing the product stream in the calibrating means, said measuring including determined by the measuring means a first weight value, said weighing includes determined by the calibrating means a second weight value;
- and further comprising the steps of comparing the second weight value and the first weight value by an evaluating electronic device;
- and in the event of deviation of said weight values from one another, multiplying by the measuring means the first weight value by a correction factor to eliminate a difference between said second weight value determined by the calibrating means and the first weight value determined by the measuring means.
