ABSTRACT:
A process and apparatus for measuring moisture content of moisture-stratified sheet material such as paper is disclosed. The effective reflectivities of two areas of an infrared moisture sensor that generally face opposite surfaces of the sheet are made significantly different, so that the sensitivity of the measurement to conditions prevailing in a high-moisture stratum of the sheet is increased.
