This dataset is a run to failure library, of differential pressure time series for a gel filter in a chemical plant. In the original publication, we used the dataset to predict the Remaining Useful Life of the filter; domain knowledge from the plant operators dictates that the filter needs to be replaced when the differential pressure has increased to 2.4 bar, from its base level of 0.2 bar. You can read more about the background of the Gelfilter dataset in Section 4.1 of the original publication. Additional background information is provided in the readme document in the zip file.
