10. measurement It has been noted for many years that the variation of the dielectric constant of hygroscopic materials against moisture content is approximately linear over a limited but useful range of 1 35 moisture content The dielectric constant of water is 81 whereas the dielectric constant of most materials of vegetable origin is quite low ranging from 2 2 to 4 0 in a dry condition The presence of a very small quantity of water in the material will therefore cause a considerable change in the dielectric constant This direct link between moisture content and dielectric constant enables Sinar Analyzers to predict successfully the Moisture Content of a wide range of samples The Problems The relationship between moisture content and dielectric constant is complicated by several factors The problems and the solutions that Sinar Technology applies to them can be summarised thus Problem Inconsistent and high sample temperatures that inherently change the dielectric constant of samples Solution Measure the sample temperature and the dielectric constant simultaneously and compensate accordingly CALIBRATION ADJUSTMENT The Sinar Model 6060 comes pre calibrated with authorised com modity calibrations Sometimes it is useful to be able to adjust the moisture reading For instance when a different oven test is used or when the particle size of a product is significantly different or when two indirect instruments are being matched
