Abstract

PURPOSE:To measure the percentage of moisture content without being subject to the influence of the width of a body to be measured, by mounting a width detecting means of the body to be measured near a hole, which inserts the body to be measured, of a box body of this detector utilizing the absorption of microwaves. CONSTITUTION:The following parts are installed; a waveguide 3, to which H surface a slit 4 running parallel in the progressive direction of microwaves is formed, a microwave generating means for supplying the microwaves to the waveguide 3 and a detecting means of the microwaves propagated in said waveguide. This moisture detector is constituted by disposing a width detecting means of a body to be measured near a hole for inserting the body to be measured of the waveguide 3. For example, an image sensor 7 is mounted to the both ends of the slit 4, into which wood 5 is inserted, as a detecting means, the locations of the both ends of the wood 5 are detected, the width of the wood 5 is measured, and the value of the percentage of moisture content obtained by correcting the effect of the width is displayed. Thus, the percentage of moisture content can accurately be measured without being affected by the width of the body to be measured.
