Rosemount Analytical 370XA gas chromatograph - Natural Gas Custody Transfer Metering

Designed to address some of today’s toughest measurement challenges in the upstream and midstream natural gas markets, Emerson introduces the Rosemount Analytical 370XA gas chromatograph (GC) for C6+ BTU / CV applications, including custody transfer, power generation and burner fuel/air ratio control. Meant to operate unattended in even the most extreme weather conditions and withstanding ambient temperatures within -20 °C to 60°C (-4 °F to 140 °F), the smarter, compact, and more economical 370XA features advanced technology, improved diagnostics, and an intuitive local operator interface (LOI ). Built-in software assistants included in the LOI guide the user through common operation and troubleshooting tasks, greatly simplifying the installation, startup, commissioning and on-going maintenance of the 370XA.

A unique innovation of the 370XA is its Maintainable Module™ technology. It incorporates the GC’s analytical components inside of a module that can be easily maintained or replaced at the component level in the field in most cases, substantially reducing repair costs and downtime. If the module needs more serious repair, a replacement module can be installed while the damaged one is sent to the lab or back to the manufacturer for further inspection. Upon replacing the module, the GC will automatically begin to self-diagnose and self-calibrate, doing much of the startup on its own and getting back online without having pressed a button.

Emerson In-Situ Flue Gas Oxygen Analyzer

Rosemount Analytical is the leader in oxygen flue gas analyzer technology. The 6888 continues the tradition of integrating an oxygen probe and field electronics into a single, compact package. The probe inserts directly into a flue gas duct to measure oxygen in combustion processes. No sampling system is required, and the newest version offers an optional on-line automatic calibration capability embedded within the probe, freeing up your technician’s time, and ensuring the most accurate O2 readings over time.

The 6888 in situ O2 transmitter provides accurate measurement of the oxygen remaining in the flue gases coming from any combustion process. Optimal combustion efficiency can be obtained by maintaining the ideal level of oxygen in the flue gases coming from these processes and the lowest level of NOX, CO and CO2 are produced.

Easy to use and easy to integrate. This in situ analyzer was designed with customer ease-of-use in mind. There are no moving parts or sampling apparatus resulting in an extremely reliable probe that requires very little maintenance.

Specifications:

  • Net O2 range: variable 0-10% to 0-50%(Xi electronics offer 0-50% O2 range)
  • Accuracy in oxidizing conditions: ±0.75% of reading or 0.05% O2, whichever is greater
  • Lowest detectable limit: 0.02% O2
  • Process temperature effect: less than 0.05% O2 from 100-700°C
  • System speed of response to calibration gas: Initial response in less than 3 seconds, T90 in less than 8 seconds. Response to process gas changes will vary, depending on process gas velocity and particulate loading of the diffuser
  • Calibration validity: Presentation of calibration gases matches the normal process to within ±0.02% O2
  • Accuracy in reducing conditions: ±0.1% of reading, or 0.1% O2, whichever is greater
  • System response in reducing conditions
  • going from oxidizing to reducing -T90 in 120 sec.
  • going from reducing to oxidizing -T90 in 30 sec.

Integrated Condition Monitoring with Dynamix 1444 Monitor helps prevent Downtime

Manufacturers can monitor and protect machinery at a lower total cost of ownership with the Allen-Bradley Dynamix 1444 Series monitors from Rockwell Automation.  The new integrated condition-monitoring system allows manufacturers to leverage the Rockwell Automation Integrated Architecture system, rather than an isolated condition-monitoring device, to assess current equipment health, predict potential issues, and help avoid damage to critical machinery. Integration of machinery health into control architectures using a standard Ethernet TCP/IP EtherNet/IP network brings unprecedented flexibility to machine instrumentation design and operational efficiency on the manufacturing floor.

“Industrial producers need a device that performs the full scope of protection and condition monitoring, and the Dynamix 1444 monitor does that while improving the ease of use and cost of such monitoring,” said Pat Carle, product manager, Rockwell Automation. “The monitors can serve a broad range of applications because they are massively configurable.”

Primarily used as a machinery protection system for rotating and reciprocating equipment, Dynamix 1444 monitors supervise critical operating parameters in real time. They also provide operations and maintenance personnel with the information to assess current equipment health and perform predictive-maintenance planning.

To protect equipment, the Dynamix 1444 device measures and monitors a machine’s critical dynamic and position parameters, and assures appropriate actions are performed with the precision, reliability and performance required by industry and regulatory standards.

A helping hand for local monitoring and control of actuators in inaccessible locations

The new Remote Hand Station enables safe and secure local monitoring and control of Rotork IQ3 actuators installed in inaccessible locations.   Rotork’s superior solution provides the user with an exact duplicate of the actuator’s own monitoring and control interface, at a distance of up to 100 metres from the valve. Power for the Remote Hand Station is supplied by the actuator, with which the unit shares all the benefits of the same IP68 double O-ring sealed environmental enclosure. There is no need for expensive cabling; standard comms wiring suitable for the operating environment is all that is required between the actuator and the Remote Hand Station.

The user can remotely operate, interrogate and configure the actuator using the Rotork hand-held setting tool with its secure wireless Bluetooth link. Retaining all of the actuator’s functionality, the Remote Hand Station presents an identical window into the process, showing diagnostic data including the valve torque and usage profiles along with service logs and facilitating real time analysis directly at the unit.

Alternatively, information from the actuator datalogger can be downloaded and transferred to a PC for analysis using Rotork Insight2 diagnostic software to enable valve maintenance requirements to be identified and anticipated.

Designed for wall or pole mounted installation, the Remote Hand Station is available with explosionproof certification and can also be equipped with a vandal proof cover to prevent unauthorised interference.

Data Loggers Monitor Bearing Temperature to Prevent Failure

The condition of the bearings in your industrial equipment is tied to the condition of your machinery and your process itself. Equipment operating at high temperatures or at low speed is prone to premature bearing or gear failure, which can cause a process shutdown costing many hours of lost production. Now CAS DataLoggers can supply your business with wired and wireless temperature monitoring systems for reliable condition monitoring and alarming of bearings in process-critical equipment including compressor motors, turbines and conveyors.

Use a temperature data logger to monitor the condition of your bearings and help predict failure before it can happen. When temperatures go out of spec, these systems automatically send out text and email alarms warning you of extreme temperatures possibly indicative of imminent bearing failure so your facility has enough notice to take corrective measures and schedule downtime for replacement.

Whether you’re running equipment at slow or high speeds, temperature monitoring is the surest way to detect bearing damage. However, manual methods of inspection can be unreliable and difficult to make time for. Bearings can gradually corrode and deteriorate, developing looseness, faults or skidding without anyone being aware. Especially at low operating speeds, it can be difficult to identify developing problems just by the occasional ‘look and listen.’ This often means that bearing damage is only noticed after it’s already too late, which can cause the equipment to fail and force a critical process shutdown. With this in mind a temperature monitoring system is the most reliable way to help prevent unplanned shutdowns and/or damage to nearby machinery.
