Moisture measuring method and apparatus

摘要

Moisture in wood veneer strips received from a drying oven is measured by passing a first radio frequency signal through the veneer for reception by a receiving plate, transmitting a second radio frequency signal in out-of-phase relation to the first radio frequency signal for reception by the receiving plate, the second signal not passing through the wood. The first and second radio frequency signals induce a potential in the receiving plate, the induction of the first radio frequency signal varying in accordance with the moisture contained in the veneer. The potential of the receiving plate is then measured to determine the extent of moisture in the veneer.
