摘要：
Moisture measurement in industrial applications, both in liquid and solid materials, presentsa significant challenge. In the field of biofuels, this becomes even more critical. Among the various approaches developed for this purpose, indirect electromagnetic techniques have emerged as a valuable tool for accurately estimating moisture content. These techniques utilize the complex dielectric permittivity “ as an intermediary parameter, which is in influenced by the water content in the material. As a first step toward this purpose, a 1′′5/8 two-port coaxial transmission cell, developed at LNE-CETIAT, was studied to make dielectric measurements on liquids. Characterization and validation steps were requested to demonstrate the accuracy of this cell. For this purpose, an intra-laboratory comparison has been performed first at LNE-CETIAT using the 1′′5/8 cell and EpsiMu® coaxial cell | a fully validated reference tool. Then, an inter-laboratory comparison with the Fresnel Institute has been performed using a coaxial probe and another EpsiMu® cell. The measurements were carried out under identical ambient conditions, using liquid reference materials. In this work, the performance of the developed cell in the frequency band [0,1-1,1] GHz has been validated, as well as the accuracy of the three electromagnetic techniques used. The results of the experiments confirm the effectiveness of the 1′′5/8 cell developed at LNE-CETIAT for measuring the dielectric properties of liquids. © 2023, Electromagnetics Academy.
