Abstract: Systems and methods include a method for monitoring sensors. Readings of actual field sensors corresponding to virtual sensors of a virtual model are monitored. A deviation between an actual sensor reading (ASR) and a virtual sensor reading (VSR) is determined. When only the VSR is deviating and when sensor readings of sensors proximate to the actual sensor correspond to the VSR, then the ASR is invalid and the actual sensor requires revalidation/recalibration. When only the ASR is deviating and when sensor readings of sensors proximate to the actual sensor correspond to the ASR, then the VSR is invalid and the virtual sensor requires revalidation/recalibration. When both the VSR and ASR are deviating from design ranges and when sensor readings of sensors that are proximate to the actual sensor do not correspond to either the ASR or the VSR, then both the ASR and VSR are invalid, requiring revalidation/recalibration.
