  • Publication number: 20100082122
    Abstract: Methods and systems for assessing transmitter electronics in an industrial process control system comprise generating a process condition reference equation signal, a process condition approximation equation signal, and an accuracy output signal. The process condition reference equation signal is generated using a process condition reference equation and process control inputs. The process condition approximation equation signal is generated using a process condition approximation equation that approximates the reference equation using the process control inputs, and approximation equation coefficients based on the approximation equation and the process control inputs. The approximation equation signal is compared to the reference equation signal at a control room workstation such that the industrial process control system can be adjusted. In one embodiment, the approximation equation coefficients are adjusted and transmitted to process transmitter electronics over a control network.

  • Publication number: 20090211368
    Abstract: A device comprises a sensor tube for placement in a process flow and a flow-modifying element. The flow-modifying element is formed on the sensor tube, in order to reduce flow-induced vibrations by reducing coherent vortex shedding in the process flow.

  • Patent number: 6935156
    Abstract: A pressure sensor of a process device, is characterized by applying a plurality of pressures to the process sensor. Outputs of the plurality of pressures are received. A compensation relationship is determined based upon the pressure sensor output. The characterization data is collected in a distribution which is non-uniform across the pressure range.
