With the high speeds of today’s green end conveyors it is virtually impossible to maintain direct contact between the wavy veneer and the RF heads, and this means that very inaccurate sorts occur, especially within the high moisture content veneers where RF sensor heads have been proven to be most inaccurate at moisture measuring. This is a significant issue with RF heads; their inability to read moisture contents above the fiber saturation point (FSP) of approximately 40% provides significant inaccuracies and it is this limitation that makes them very ineffective for measuring the M/C within not only the wetter sections of the wood, such as the sap and heavy sap portions, but as well as throughout the wetter species such as southern yellow pine.
