  • Transducer fault detection system using slew rate measurements: apparatus and method
    Patent number: 6816816
    Abstract: A transducer fault detection system that transforms transducer measurements into slew rate measurement, and determines which, if any, of the slew rate measurement are anomalous or correlative to faults. The system can generate alarms based on these determinations. The system may also transform transducer measurements into digitized voltage measurements, determine how long a succession of the digitized voltage measurements remain within at least one defined voltage window, and determine if there is a correlation between the determined time duration of digitized voltage measurements and an anomalous condition. Each determined anomalous condition may then be associated to a defined fault for gaining fault specificity.
