Abstract
The thickness of a web is measured by passing the web through the gaps of a loop-gap resonator. Changes in web thickness alter the resonant frequency of the resonator which is detected by a control circuit. Three embodiments of the invention are described, and in one embodiment, the moisture content of the web is also measured.
