摘要: The differential dielectrometer was designed to measure small differences in complex permittivity (CP) of two high loss liquids at frequency 32.82 GHz. measurements are fully computer-aided with the exception filling and draining measurement cells. time one cycle does not exceed 3 min. is easy-to-work can be used under conditions scientific industrial physical–chemical laboratories. sensitivity difference phase coefficients electromagnetic waves propagated cells better than 0.05% that attenuation coefficient order 0.2%. contains dielectric quartz cylinders surrounded by liquids. We developed CP calculation algorithm using known reference liquid wave propagation origins errors studied detail recommendations were made avoid some them. express identification wine must authenticity means their values. results for solutions substances make composition obtained. possibility detection added water wines or musts shown.
