System and method for retroactive and automated validation or corrective action with respect to online sensors

A system comprising:

• one or more first sensors mounted online with respect to an industrial process, and configured to generate first data corresponding to measured variables in real time for at least one respective process component;
• data storage aggregating the first data as respective input data points with corresponding contextual tags comprising time series identifiers;
• and
• a data processor configured, for a given sample collected from a production stage of the industrial process and having a respective time series identifier, to
• obtain at least the respective input data point of the first data having a corresponding time series identifier,
• collect second data via one or more second sensors, the second data comprising measured variables corresponding to the at least one respective process component from the given sample,
• determine a difference between at least one measured variable from the first data and the corresponding at least one measured variable from the second data, and
• selectively generate a feedback signal to at least one of the one or more first sensors as an error value based on the determined difference;
• wherein a controller is functionally linked to the at least one of the one or more first sensors and configured to automatically correct further first data generated from the at least one of the one or more first sensors based on the generated feedback signal.
