    Abstract: A process variable transmitter (60, 82, 230, 232, 234, 238) with diagnostics based on power spectral density (PSD) analysis of a process variable sensor signal is provided. In one embodiment, the process variable transmitter (60, 82, 230, 232, 234, 238) is a pressure transmitter (82) and the diagnostics are used to diagnose impulse line obstruction or impending obstruction. Other diagnostics are also useful such as diagnosing primary element degradation. The sensor signal is digitized and the digitized signal is transferred into the frequency domain. The power of the frequencies on the sensor signal is examined to provide the enhanced diagnostics. In one aspect diagnostics are generated directly with the sensor PSD data. In another aspect, the PSD analysis is used to tune a filter in order to enhance traditional diagnostic algorithms.

    Abstract: A flow diagnostic system (100) for a flow sensing element and impulse line (104). A pressure transmitter (102) coupled to the impulse lines (104) provides digital pressure data to a control system (112). The control system (112) provides the pressure data and real time clock readings to a diagnostic application (130,132 or 134). The diagnostic application (130,132 or 134) calculates a difference between current pressure data and its moving average. A condition of the primary element or impulse lines is diagnosed from a current pressure data set relative to an historical data set. The application can run on the control system (112), a remote computer (122) or an ASP application service provider (126).

    Abstract: A pressure transmitter (50) with an output (88) predicting the magnitude of error in the pressure transmitter's output (57). A pressure sensor (72) is adapted to sense a process pressure (74). A controller (76) coupled to the pressure sensor (72) generates a transmitter output (78) representing the process pressure (74). A memory (80) stores predetermined data predicting magnitudes (82) of transmitter output error as a function of cumulative excessive sensor output levels, and also stores a record of cumulative excessive sensor output levels (86). The controller (76) 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 (88).

    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).
