Abstract

Caliper measurement and control is a vital part of papermaking. But this measurement can be a challenge. Over the years, various mechanical and optical sensors have been invented to achieve the best combination of accuracy, no sheet damage and reliable operation. <BR>Some caliper sensors utilize laser triangulation. There are several inherent accuracy problems in this method, one particular problem known as light penetration. Grade-dependent and process-dependent calibrations or other compensations may be required when utilizing a laser caliper sensor.<BR>In this paper, we present a new, optical on-line measurement that measures caliper without laser triangulation, thus vastly reducing errors and provide a more reliable measurement. This new method can also detect very small scale variability of the sheet. Findings on a production paper machine will also be discussed.
