Abstract
A system for determining the edge of a continuous web and which compensates for non-uniformity in dielectric response, including thickness is disclosed. The invention comprises first electrode for outputting a signal corresponding to the edge position of a continuous web; and second electrode associated with said first electrode for outputting a second signal corresponding to the thickness of the web, such changes in the output signal of the second electrode are related to the output signal of the first electrode.
