Progress on Capacitive Sensing for Real-Time Process Tomography

Abstract

We report on recent progress in the development of capacitive sensors for real-time tomography of industrial processes. In particular, we describe recent developments on: (1) adaptive electrical capacitance volume tomography (AECVT) sensors based on reconfigurable synthetic electrodes, (2) multifrequency acquisition strategies exploiting the Maxwell-Wagner-Sillars effect in multiphase flows, (3) displacement current phase tomography for imaging of fluid flows, and (4) flow velocity profiling based on electrical capacitance volume tomography (ECVT) sensors.
