<p>In one embodiment, the proposed moisture gauge comprises: a modulated infrared source (1); a control (2) with zero moisture content; a control (3) with a fixed moisture content; the material under investigation (4); an optical sensor system (5); three photosensor units (6, 7, 8) with demodulators; two correction units (9, 10); a subtraction unit (11); two addition units (12, 13); a unit (14) for multiplication by a constant; a division unit (15); and a display unit (16). This design preserves a linear relationship between the output function and the measured moisture.</p> |
