Anomaly detection and removal strategies for in-line permittivity sensor signal used in bioprocesses

IntroductionIn-line sensors, which are crucial for real-time (bio-) process monitoring, can suffer from anomalies. These signal spikes and shifts compromise process control. Due to the dynamic and non-stationary nature of bioprocess signals, addressing these issues requires specialized preprocessing...
