Abstract

PURPOSE: To linearize the change of a voltage value over an entire range from low moisture to high moisture regions and display it in a single range by passing a current flowing through a measured sample such as cereals through a current-voltage converting circuit with a feedback passage and taking out a voltage corresponding to the current value.
CONSTITUTION: The change of a current which flows through a measured sample Rx such as cereals is taken out as the change of a voltage and water content percentage corresponding to the resistance value of the sample is measured: in the feedback passage of a current-voltage converting circuit, a diode D1 and a resistor R4 are connected in series. By such a constitution, a current which flows through the measured sample Rx is converted into a logarithm, is converted into a voltage corresponding to the current value and taken out, and low moisture and high moisture regions are displayed in a single range and on a linear scale.
