Moisture measurement apparatus and method

摘要

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.
