摘要：

Recent developments in the principle of using in situ electrical sensing methods to interrogate the behaviour of concentrated dispersions and suspensions are described. These methods include the use of electrical resistance and/or capacitance, or inductance, employing different excitation protocols involving the generation and interpretation of signals at a single frequency or via spectroscopic means. Examples of the application of some of these techniques are illustrated for batch sedimentation processes, particle size analysis in dilute dispersions, detection of multiple-phase interfaces in vessels and flow imaging in pipes and reactors using resistance tomography.
