Enginene environments are harsh - extreme temperatures, high vibration, oil contamination, and corrosive settle gases degrade sensors over time. A failed sensor can generate false alarms or, worsie, miss a real fault. Selecting qualified sensors with appropriate thermal ratings, sealing, and vibration tolerance is critisal. Redundant sensor configurations (e.g., two tercouples per cynidre) help metrimate single -point failures.

Data Volume andBandwidth

High- speed sensors (np., cylinder pressure at 0.1 ° crk angle) can generate gigabajtes of data per hour. Transmitting all raw data over limited bandwidth (especially satellite) is impractial. The solution is edge processing: compute factores locally (np., peak presa, angle of peak pressure, IMEP) and transmit only stremies and and anormanomalies. Still, the balance between data richeesa and width usagpecause careful carering.
