Many Vibration Programs Fail Because They Become Too Complicated —Keep Things Simple

Many vibration programs fail because they become too complicated. Too much data can sometimes become more confusing than too little data. Many potential machinery problems can be eliminated with

Meggitt’s Wilcoxon Research M12-style Accelerometers and Cable Assemblies

Meggitt Sensing Systems, the makers of Wilcoxon Research vibration sensors and sensor networks, has added three new accelerometers with M12 connectors to its product line. The M12 connector makes it easy to implement vibration monitoring where the existing infrastructure is already built around the M12 standard, such as the process industries. Several compatible M12 connector-cable assemblies are also now available.

Meggitt Sensing Systems Facility Renews AS9100, ISO 9001, and ISO 14001 Certifications

Meggitt Sensing Systems, the manufacturer of Wilcoxon Research vibration sensors and sensor networks, passed annual audits to keep current the Germantown facility’s AS9100 Aerospace Standard for Quality Systems, ISO 9001 Quality Management System, and ISO 14001 Environmental Management System certifications.

Endevco, Ferroperm, Vibro-Meter, Sensorex and Wilcoxon Combine into Single Meggitt Sensing Division

The Meggitt group is making the transition to a new structure comprising five operating divisions: Meggitt Sensing Systems, Meggitt Aircraft Braking Systems, Meggitt Control Systems, Meggitt Polymers &  Composites and Meggitt Equipment Group.  Based on core capabilities, this is designed to build stronger, more integrated operating divisions.  The transition should be completed in 2010.

Balancing a Generator at a Hydro Electric Plant

Just two years after installation of a new turbine-generating unit at the 93-MW Thompson Falls hydro project, PPL Montana LLC noticed increasing vibration values on the generator guide bearing. After several unsuccessful attempts to correct the problem, plant personnel adjusted the clearance on the guide bearings. Since that work was completed, the unit has operated within acceptable vibration values.

Refining a Refiner with 4-20 mA Monitoring

by Ed Nisbett, Tim Gilliss and Tom LaRocque

In their mill that is located in East Millinocket, ME (“The Town that Paper Made”), Katahdin Paper Company, LLC, produces pulp, which is used in the production of directory paper, from two paper machines.  Prior to paper production, the characteristics of the wood pulps are adjusted accordingly by passing them through a refiner with patterned rotating plates (see Figure 1).

How Do You Analyze Spectra?  Do You Miss Key Information?

If you follow an organized process, the time spent analyzing spectra will be far more effective. Here is a brief review:

1. Ski-slope check: Quickly check for ski-slope in case it was a bad measurement. Check the time waveform to see if you can determine what went wrong during the measurement.

2. Noise floor check: Noise can indicate that impacting or rubbing

Wilcoxon Research Safety Connector Cables for Portable Data Collection

Wilcoxon Research, a Meggitt group company and a leading supplier of quality vibration sensors and sensor networks, is broadening its line of MaxFlex cables for portable data collectors to include an optional safety connector that breaks away if the sensor or cable becomes entangled at the monitoring point.

When collecting vibration data, it is important to keep the operator safe from being dangerously pulled toward a machine. Safety connector cables for data collection will protect the operator during a data collection route by disconnecting the sensor from the data collector when more than 10 pounds (4.5 kilograms) of pull force is exerted. Additional benefits of this safety feature include preventing damage to expensive portable data collector hardware and providing a quick disconnect between the sensor and the data collector.
