“…This is for example the case in pneumatic conveying, where the particulate matter causes abrasion on the sensor. Publications on electrical tomography systems cover all aspects of these measurement systems such as the sensor design [13][14][15], and the measurement electronics [16,17]. The bulk of publications can yet be found in the field of signal processing and image reconstruction methods [18].…”

The application of electrical capacitance tomography (ECT) for monitoring of industrial processes has been studied and proposed by many researchers. Examples can be found in monitoring of multiphase flows or mixing processes in reactors. Demonstrations of the functionality based on lab and test rig measurements have proven the potential of the proposed principles. This paper discusses the application of an ECT system in a heavy industries application. The harsh operating conditions in the industrial environment pose several challenges for the application of sophisticated measurement technology. This work addresses key aspects for the application of an ECT measurement system in such an environment. Specifically the electrical system design and the influence of the temperature are addressed. Relevant parameters and possible solutions are discussed. Furthermore the application of ECT as instrument for mass flow metering in pneumatic conveying processes is addressed. Supportive measurement studies from test rig experiments and comparative simulation studies are presented. Therefore, the paper provides a concise discussion on the application of ECT under harsh operating conditions, as well as the use of ECT as a measurement device for process measurement. The work concludes with a presentation of a measurement system in an industrial plant in which the proposed concepts were succesfully implemented.

Metallic spheres play a crucial role in industry and their accurate measurement is essential to ensure the safety of industrial production. Eddy current testing (ECT), which is non‐contact and non‐invasive, provides an efficient and precise approach for the parameter evaluation of metallic spheres. In this paper, we utilize machine learning (ML) methods to invert inductive signals in order to address the inverse problem of ECT, with the aim of reconstructing the radius of a metallic sphere. Datasets containing the radius information of the metallic sphere were constructed based on the simplified analytical solution. The datasets were divided into two parts based on the real part (RP) and imaginary part (IP) features, and the connection between the two features and the radius of the metallic sphere were compared by five classification models. While achieving accurate classification of aluminum and stainless steel spheres with different radius, the models are evaluated to ensure the reliability and validity of the models. The results show that the use of IP data as a classification feature has better accuracy as compared to RP. The K nearest neighbor (KNN) radius classifier has the highest accuracy of 95.5% in aluminum spheres and the random forest (RF) radius classifier has the highest accuracy of 95.9% in stainless steel spheres. In addition, all five classifiers are able to overcome the effect of lift‐off on the classification results.
