  • Patent number: 6708555
    Abstract: A wood moisture meter for measuring the moisture content of wood by monitoring the dielectric constant of the wood as a dependent variable of the amount of moisture in the wood. The sensor is a pair of parallel plates which, when encased in a plastic film, placed side by side in direct contact with the wood and in a snake-like pattern, will form the plates of a capacitor in the which the dielectric material is the wood itself. The capacitor is used in a circuit, the input for which is a nominal voltage of 5V, the output of which is a pulse of a length directly proportional to the varying dielectric constant of the wood as the wood dries in a wood drying kiln. The pulse length is correlated with the appropriate wood moisture content and provided to the operator of the kiln.
