Mounting Digital Valve Controller Howto Video

It has been a busy week as many of the experts around Emerson Process Management here in Austin to work on ways to improve their participation in the social channels.

I wanted to share a “how to” video, Mounting a Fisher FIELDVUE DVC6200 Digital Valve Controller to a 657 Actuator.

In it, Engineering/Industrial Management student and former Emerson intern James Holloway shows the process of mounting the DVC6200 instrument on the Fisher 657 spring-opposed diaphragm actuators. Continue Reading

Avoiding Rotating Machinery Downtime with PeakVue Diagnostics

We all appreciate the diagnostics in our cars that provide early warning to get a problem fixed before a breakdown occurs. We’ve chronicled how rotating machinery diagnostics, such as PeakVue Analysis diagnostics, can provide early warning to avoid unplanned shutdowns.

Emerson's Jacob Swafford


Emerson’s Jacob Swafford shared several PeakVue examples with me. A North American cogeneration power company was alerted to a high 2x peak with harmonics on a boiler feed pump motor’s inboard bearing. As this peak level increased, a machinery vibration analyst identified the problem as looseness in the bearing housing causing the bearing case to turn with the motor shaft.

The repair could be scheduled instead of worsening to the point of failure and causing a loss of electrical power for their customers.

A second example Jacob shared was at a chemical manufacturing plant. An increase in vibration on a gearbox shaft outboard bearing was flagged for the watch list and data analysis was increased in frequency to once every other week. This gearbox was on a critical agitator that runs in a batch process. Continue Reading

Optimizing Life Sciences Processes by Improving Data Integration

Life-Sciences-Data-IntegrationPharmaceutical and biotech manufacturers face many economic and technical challenges including reduced prices and diminishing profits, rising research & development costs, increasing regulatory requirements and a greater need for optimized manufacturing operations.

Emerson's Ritesh Patil


In a Pharma Bio World article, Data Integration Challenges and Solutions for Life Science Industry, Emerson’s Michalle Adkins and Ritesh Patil describe ways to address these challenges.

They note that multiple systems require people and workflows, and:

…the paper batch record is the glue that holds everything together. In this paradigm, these different levels of automation with the paper batch record do not provide optimal, efficient solutions for integrating business data and ensuring data integrity.

From a data integrity standpoint, challenges stem from mixed levels of automation, islands of automation of different platforms and manual and paper processes. Continue Reading

Improving Regulatory Control Performance

Emerson's James Beall


Emerson Global Users ExchangeOne of the presenters I really enjoy listening to at Emerson Exchange conferences is Emerson’s James Beall. As a process control consultant, he helps process manufacturers and producers get their processes running as optimally as possible.

He always shares his tips and tricks from understanding the dynamics of a process to how to get the most out of the PID algorithm.

Here’s a video from last year’s “Meet the Experts” session on DeltaV Regulatory Control Performance (1:27:42). James moderated this panel of experts as they discussed the importance of a solid control foundation, techniques on identifying issues and ways to fix these issues. Continue Reading

Rotating Machinery Protection and API Standard 670

For those managing the reliability for large complexes such as refineries and petrochemical plants, protecting the rotating machinery that can number in the hundreds can be a daunting task.

Emerson's Gary Hawkins


Recently a refinery manager asked Emerson’s Gary Hawkins about options for protecting their 400+ rotating machines and the application of the API Standard 670 [$195 USD purchase price] in this effort.

Gary checked with Emerson’s Deane Horn for how this machinery protection standard has been applied. Deane explained that the API 670 is a vibration monitoring, rotating machinery shutdown protection specification and does not address seal systems such as API Standard 682 for pumps.

The typical requirements for a system to be in accordance with this purchasing specification are: 100 msec reaction time, redundant power source, redundant communications, shutdown voting logic, configurable for failsafe or availability, Modbus, accuracy specification, radial vibration, axial thrust position, temperature, case vibration, and remote relay bypass, to name a few of the key ones.

Deane noted that API Std 670 is a purchasing specification. Products cannot be certified and it is up to the end users whether to implement this level of machinery shutdown protection. API Std 670 can be applied to any rotating machinery including turbines, compressors, pumps, gearboxes, etc. Continue Reading
