Abstract

A property of a paper web is measured using one or more reflectance measurement sensors emitting measuring beams onto the web and receiving the beams reflected from the web, from which the web property is deduced. The web is supported on a web support during the measurement, such as on a passive or active airfoil or fabric. One or more measurement sensor(s) can be integrated within an active airfoil, and can comprise a plurality of optical fibers having sensing ends arranged in the airfoil such that the sensing ends of the fibers face the moving paper web through one or more apertures in a web-supporting panel of the airfoil. Alternatively, a traversing sensor can be mounted within the airfoil. Other embodiments include a reflectance sensor mounted adjacent an airfoil or other web support such as a through-air drying fabric or a support belt for the web.
