摘要： A field device (20, 200) includes diagnostic circuitry (36) adapted to measure a characteristic related to a process control and measurement system (10). The measured characteristic is used to provide a diagnostic output indicative of a condition of the process control and measurement system (10). The measured characteristic can be provided to a diagnostic module that operates upon the measured characteristic to predict, or otherwise model, a condition of the process control and measurement system (10).

摘要： A field device (8) includes circuitry to successively measure a parameter related to current measurements are provided to a prediction engine which calculates a diagnostic output based upon the plurality of current-related measurements. The diagnostic prediction provided by the prediction engine can provide an estimate of viable life remaining for the device electronics. The diagonstic feature provides on-line status of the overall status of the field transmitter.
