PURPOSE:To make measurement of moisture contents of cereal grains accurate, by correcting a variation of an output between electrodes due to the number or the husk thickness of the cereal grains. CONSTITUTION:Counter electrodes 1a, 1b which are approachable and removable to and from each other by motor driving are provided, the cereal grains are pressed and crushed by each electrode to detect the moisture contents electrically. In this case, a circuit 2 compensating the output between the electrodes in accordance with a load current of the motor M is provided, and the variation of the output between the electrodes are compensated by the number or the grain pressure of the cereal grains to be pushed and crushed. |
