    摘要: A system for detecting abnormal situations associated with a heater in a process plant receives statistical data associated with the heater unit. The statistical data is analyzed to detect whether one or more abnormal situations associated with the heater exist. The statistical data may comprise statistical data generated based on pressure variables sensed by one or more pressure sensors associated with a furnace, a stack, a fuel supply, etc., associated with the heater. Additionally, the statistical data may comprise statistical data generated based on temperature variables sensed by one or more temperature sensors associated with the furnace, the stack, etc. If an abnormal situation is detected, an indicator of the abnormal situation may be generated.

    摘要: A process variable transmitter with diagnostics based on power spectral density (PSD) analysis of a process variable sensor signal is provided. In one embodiment, the process variable transmitter is a pressure transmitter 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.

    摘要: 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.

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