Moisture calibration of an R.F based inline moisture sensor : An inline moisture sensor based on radio wave attenuation, Microtec M3 Scan, was calibrated to maximise correlation between real water content in wood and received signal

Abstract: Sensors based on radio waves are used for inline moisture determination in the sawn wood industry. Placed at the final sorting line such a device can be invaluable, giving the operators real time information on the moisture content of the boards passing through. Information that can then be used to improve process control both upstream and downstream. The equipment must first be trained to correlate radio wave attenuation and phase shift to water conten
