b'MICROWAVE TECHNOLOGY APPLICATIONSSimplified Side Elevation Drawingsheet to be as far as several millimeters away from the sensor head, and still obtain a high accuracy and precision (+/- 1gsm water content).This unit is being evaluated for the holy grail of tissue manufacture, i.e. measuring Post Pressure Roll Consistency (PPRC) on the Yankee dryer itself. As work progresses, additional papers will be made public. CASE STUDY 1For The last 15+ years, the greatest expansion in the paper industry has been the TAD segment. The complexity of these machines frequently present challenges to the installation of instrumentation, but recent work with paper companies has shown that microwave moisture measurement is possible and provides accurate sheet moisture levels without the need for grab samples.Obtaining grab samples can be a safety risk, and the lab-measured Figure 4.
