Technical Abstract: A microwave moisture measurement technique was developed at the USDA, ARS Cotton Production and Processing Research Unit for moisture sensing of cotton bales after the bale press. The technique measures the propagation delay of a microwave signal that is transmitted through the cotton bale. This research conducted a controlled laboratory experiment as well as a field trial to test the sensor in a commercial cotton gin that is utilizing moisture restoration systems. The laboratory test’s accuracy was found to be 0.35% moisture content. The field trial produced similar results on commercial cotton bales. These results indicate the sensor has the potential to provide a reliable non-contact measurement of the moisture content of cotton bales, even with moisture restoration systems.
