Abstract

The drying time of a piece of wood can be determined by the present apparatus and method, based on a current signal passing through the piece of wood. A set of first and second electrodes of a probe are inserted into the piece of wood which may be travelling on a conveyor. The second electrode has an input for receiving electric power. The first electrode has an output for transmission of the current signal having passed through the piece of wood. The probe is driven toward and away from the piece of wood by a driving mechanism controlled by a control circuit. A measuring circuit is coupled to the outputs of the electrodes. The current signals are measured by the measuring circuit, which determines the drying time of the piece of wood.
