Electrical impedance tomographic sensor systems

This paper reviews aspects of the current status of process sensing using electrical impedance process tomography. This new sensor technology offers a unique insight into a wide range of industrial processes. Applications include a range of processes that feature complex flows and multiple component interactions. The paper provides an overview of hardware and software technology in terms of an instrument currently targeted at pilot trials through a consultancy service. Finally a case study is used to illustrate a typical application in which a detailed insight into an otherwise intractable process has been obtained.
