Abstract

A set-up for measuring the average volume of wooden chips for particle board manufacturing is presented. The measurement is based on a dual-polarization forward scattering measurement combined with the free-space measurement of phase and attenuation. Laboratory measurements of the ratio of the average volumes of chips with different size distributions and permittivities are presented.<>
