PURPOSE:To enable accurate and simple measuring of moisture value of cereals through supply of a given amount of sample cereals and to enable reducing of an error due to a change in capacity, by a method wherein a sensor part consisting of electrodes having a particular structure is mounted to a measuring receptacle for measuring moisture of cereals. CONSTITUTION:A stational plate 4 is positioned to an upper side of the inside of a machine frame 1 wherein a cereals feed port 2 and an cereals discharge port 8 are formed, and a cereals conveying path, consisting of a cereals conveying gutter 6 provided with a vibrator 5, is placed on the plate 4. A scaling device 9, supported by a spring, is securely located under the plate 4, and is connected to a measuring receptacle 10. A sensor part 12 is attached to an inner wall surface of a cylinder 11 of the receptacle 10, a moisture E. Beltlike branch cathode 17, being positioned in a lateral direction at an upper part H of the substrate 16, is formed into beltlike branch cathodes 18a-18d which are arranged in comb teeth on the sensor 12, beltlike branch anodes 19a-19e are positioned at both sides of each of the cathodes 18a-18d and at each space between the cathodes 18a-18d, and they are monolithically united with a beltlike anode 20 laterally positioned at each lower part c, to form a printed plate electrode 21. This permits the high-precise detection of moisture of cereals. |
