20090267621 | Method and device for rapid non-destructive quality control of powdered materials - Method and related device intended for rapid non-destructive testing of powdered materials with low electric conductivity such as cement and cement-based compositions through determination of their electrical properties. The invention involves an electromagnetic method, including an electronic circuit for generating an electric field in a capacitance probe that is inserted into the powder to be tested. Electrical properties of powdered materials are determined on the basis of a set of the values for a set of parameters including quality factor (Q-factor), capacitance, dissipation factor, and dielectric permeability of the material. These parameter values can be related to such characteristics as moisture content, particle size, and material composition. The method and device can indicate the differences between the samples with various quantities of unwanted components or reaction products, and the extent of sample ageing. | 10-29-2009 |
