Abstract
A method for determining the moisture content of wood (1), including the operating steps of inserting the wood (1) between a first plate and a second plate (3) of a capacitor (4); applying a first signal to the first plate (2) of the capacitor (4) using the plate as a transmitting antenna; detecting on the second plate (3) a second signal induced by the first signal, using the second plate (3) as a receiving antenna; determining from the second induced signal detected, a third reference signal, obtaining a differential signal; determining the components of the differential in phase and in quadrature signals from the first signal; filtering the components of the differential in phase and in quadrature signals to obtain a filtered in phase component and a filtered in quadrature component, which are independent of the frequency of the first signal; and calculating the moisture content of wood (1) based on the value of the filtered in phase and in quadrature components of the differential signal.
