Abstract: A transducer calibration apparatus and method for transforming both previously established transducer parameters for a transducer calibrated to a first target object material and measured transducer parameters for the transducer monitoring a second different target object material into a calibration parameter and transforming the output of the transducer and thus, the use of the transducer, from the first target object material used to calibrate the transducer to the second different target object material being subsequently monitored by the transducer by linearizing the output of the transducer into gap values as a function of the calculated calibration parameter and then, generating alarms based on the linearized output of the transducer exceeding established limits and using the alarms to automatically shut down a machine being monitored by the transducer and/or automatically annunciate machine problems to personnel.

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.
