Abstract

1334791 Measuring moisture content RANK ORGANISATION Ltd 13 July 1971 [14 July 1970] 34149/70 Heading GIN The moisture content of particulate material is measured by filling a capsule 4 with the material and placing the capsule in a waveguide 3, the attenuation of microwave energy passed through being indicative of the moisture content. As shown, the capsule has an inclined, closed end 6 and a removable plug 7 having a similarly inclined face. The waveguide consists of two separable portions 1, 2. In alternatives, the end 6 may be stepped, and may be coned or tapered outwardly or inwardly, the plug having an inwardly tapered end, Fig. 3 (not shown).
