Abstract
Apparatus and method for measuring the moisture content of wood and paper products utilizing the dependency of the resistance or capacitance of such products upon moisture content. A resistance or capacitance-controlled oscillator circuit is completed by electrical connection to a product. Electrical connection of the resistance-controlled oscillator embodiment is accomplished by either application of a conducting contact grid pattern to a product or by forming a parallel plate probe incorporating the product therein. Electrical connection of the capacitance-controlled oscillator embodiment may also be accomplished by forming a parallel plate probe incorporating the product therein or by insertion of a plurality of conductive cylinders in parallel combination into flutes of a corrugated paperboard product when such a product is to be subject to measurement.
