摘要： A sensor is provided that measures web caliper using optical and magnetic measuring devices. The optical measuring devices may employ a confocal chromatic aberration method to accurately determine the distance to the moving web and the magnetic devices may be ferrite core coil and target. Means of stabilizing a moving web are included for improving dynamic measurement accuracy.
