Abstract: A diagnostic device for use in a process control system receives a sensor signal related to a process variable of a process sensed by a process variable sensor. A signal preprocessor provides a sensor power signal output as a function of a frequency distribution of power in the sensor signal. A process condition is determined based upon the sensor power signal.

Abstract: A pressure transmitter with an output predicting the magnitude of error in the pressure transmitter's output. A pressure sensor is adapted to sense a process pressure. A controller coupled to the pressure sensor generates a transmitter output representing the process pressure. A memory stores predetermined data predicting magnitudes of transmitter output error as a function of cumulative excessive sensor output levels, and also stores a record of cumulative excessive sensor output levels. The controller calculates a predicted present magnitude of transmitter output error as a function of the accumulated record and the predetermined data, and generates the prediction output.

Abstract: A two-wire temperature transmitter is coupleable to a two-wire process control loop for measuring temperature of a process. The transmitter includes an analog to digital converter configured to provide digital output in response to an analog input. A two-wire loop communicator is configured to couple to the process control loop and send information on the loop. A microprocessor is coupled to the digital output and configured to send temperature related information on the process control loop with the two-wire loop communicator. A power supply is configured to completely power the two-wire temperature transmitter with power from the two-wire process control loop. A temperature sensor comprises at least two temperature sensitive elements having element outputs which degrade in accordance with different degradation characteristics. The element outputs are provided to the analog to digital converter, such that the microprocessor calculates temperature related information as a function of at least one element output from a first temperature sensitive element and at least as a function of one degradation characteristic of a second temperature sensitive element.

Abstract: Transmitter in a process control system includes a resistance sensor sensing a process variable and providing a sensor output. Sensor monitoring circuitry coupled to the sensor provides a secondary signal related to the sensor. Analog-to-digital conversion circuitry coupled to the sensor output and the sensor monitoring circuitry provides a digitized sensor output and a digitized secondary signal. Output circuitry coupled to a process control loop transmits a residual life estimate related to residual life of the sensor. A memory stores a set of expected results related to the secondary signal and to the sensor. Diagnostic circuitry provides the residual life estimate as a function of the expected results stored in the memory, the digitized sensor output and the digitized secondary signal.

Abstract: A fluid flow meter (82) diagnoses the condition of its primary element (28) or impulse lines (30) connecting to a differential pressure sensor (31). A difference circuit (90) coupled to the differential pressure sensor (31) has a difference output representing the sensed differential pressure minus a moving average. A calculate circuit (92) receives the difference output and calculates a trained output of historical data obtained during an initial training time. The calculate circuit (92) also calculates a monitor output of current data obtained during monitoring or normal operation of the fluid flow meter (82). A diagnostic circuit receives the trained output and the monitor output and generates a diagnostic output indicating a current condition of the primary element (28) and impulse lines (30).
