Non destructive measurement method and device of suffering dry thing percentage of water content

摘要

Percentage of water content of suffering dry ones which form or character do not fix by the fact that appropriate recursive system is used with the measurement of electric quality measurement expedient, and impedance and capacitance of suffering dry ones whose form and character are uneven, offer of the expedient which with non destruction is measured in high accuracy. The measurement method of inserting suffering dry ones whose character and form are uneven in the container of specified capacity, inside the said container four electrode terminals inserting, impressing the interchange signal of specified voltage in the said electrode terminal, measuring the electric quality between two electrodes due to suffering dry ones, connecting to the high impedance voltmeter, measuring the percentage of water content of suffering dry ones with non destruction. The interchange signal of the specified voltage which is impressed in four electrode terminals 3b and the electrode terminal 3d which are inserted inside container 3d of the specified capacity which accommodates suffering dry ones whose character and form are uneven and container 3d and two electrodes due to suffering dry ones measuring the electric quality between, it has the high impedance voltmeter 2 which is input.
