Abstract:
A device [23] comprises a sensor tube {[21] for placement in a process flow and a flow-modifying element [22]. The flow-modifying element [22] is formed on the sensor tube [21], in order to reduce flow-induced vibrations by reducing coherent vortex shedding in the process flow.
Abstract:
An industrial process sensor having a sensor component exposed to process fluid detects when the sensor performance has been degraded by a sensor coating buildup from the process fluid. A baseline statistical metric, such as standard deviation of the process parameter sensed by the sensor, is determined during an initial operating period when the sensor component is clean. During continued operation of the sensor, the statistical metric is continually updated and monitored. An alarm output indicating that sensor coating has degraded sensor performance is produced when the current value of the statistical metric varies from the baseline value by an amount indicating degraded sensor performance.
Abstract:
An interface module (200) and method for operation include ports (302a-b) for communicating over a network (308) with a first protocol to a plurality of field devices (102a-n). The interface module also has a port (316) for communicating with a process controller (114) via a high speed network and protocol such as High Speed Ethernet (HSE). The interface module (200) includes a controller (320) for implementing a, plurality of process function modules (322, 324, 325), each of the plurality of process function modules (322, 324, 325) corresponding to one of the plurality of field devices (102a-n). Remote programmability, email messaging and alarms are supported.
Abstract:
An interface module is operatively coupled to a Fieldbus process control network and a Modbus process control network to facilitate the exchange of process control information between the networks. The interface module stores a register map database in which the process control parameters of the function blocks in the field devices of the Fieldbus process control network are mapped to register numbers of the Modbus process control network. Once the Fieldbus process control parameters are mapped to the Modbus registers, the interface module is adapted to transmit request messages on the Fieldbus process control network to the Fieldbus field devices for the current values of the process control parameters, receive response messages from the Fieldbus field devices, and store the current values of the process control parameters in the register map database.
Abstract:
An interface module is operatively connected to a Fieldbus process control network and to at least one non-Fieldbus process control network to facilitate the exchange of process control information between the networks. The interface module stores a database in which the process control parameters of the function blocks in the field devices of the Fieldbus process control network are mapped to corresponding process control parameters of the non-Fieldbus process control network. Once the Fieldbus process control parameters are mapped to the non-Fieldbus process control parameters, the interface module is adapted to transmit request messages on the Fieldbus process control network to the Fieldbus field devices for the current values of the process control parameters, receive response messages from the Fieldbus field devices, and store the current values of the process control parameters in the database. The interface module may also function in the other direction to map non-Fieldbus process control parameters to corresponding Fieldbus process control parameters.
Abstract:
A system for providing remote diagnostic and maintenance services to a process plant includes a database and a server, both of which are located remotely from the process plant. The database includes a plurality of applications. The server includes a data collection unit, an analysis unit, and a control unit. The data collection unit collects data associated with the process plant via a communication link, such as the Internet. The analysis unit analyzes the collected data to detect a condition associated with the process plant. In response to the detected condition, the control unit automatically implements one or more of the applications by automatically executing one or more of the applications remotely and determining parameters to be communicated to the process plant, automatically downloading one or more applications to the process plant via the Internet, and/or activating a web page that provides information for guiding an operator located at the plant in correcting the detected condition.
