For each measurement the reference capacitances for the low and high calibration of the ECT measuring system, the recorded raw capacitances, the reconstructed normalized pixel permittivities as well as the corresponding time vector are provided for the different materials. In case of the catalyst FCDS_LQ3 also the calculated pixel temperatures are provided. The averaging over time as done in the paper has not been performed with the data provided here. Electrical_impedance_data: contains the recorded impedance data used for investigating the permittivity-temperature relationship of the different materials examined. Thermocouple_data: contains the temperature measurement data recorded with a thermocouple centered in the fixed-bed at the height of the measuring electrodes. This data was used for comparison with the pixel temperatures calculated from the ECT for the catalyst FCDS-LQ3enElectrical Capacitance Tomography (ECT)Fixed-bed ReactorTemperature ProfileNon-invasiveTemperatur MonitoringDataset
