We put the spotlight on products and services for dealing with this killer of equipment and processes.
Keep The Blades Turning
Proper alignment of the drivetrain and balancing of the rotor blades are important to condition monitoring of wind turbines. Now, thanks to Ludeca’s VIBXPERT® and its OMNITREND® PC software, wind-turbine vibration signals are no longer a problem to measure and evaluate. For details, check in with LUDECAwind. It provides a variety of system support services for wind-energy operations, including installation and start-up of condition monitoring systems, telediagnosis services with remote monitoring, laser alignment and geometric measurement systems, continuous alignment monitoring and consulting.

Protection & Monitoring In One Device
SKF’s Multilog On-line System DMx is a multi-featured vibration monitor for both conventional and hazardous environments. Awarded ATEX, IECEx and cULus certifications, the system can be directly installed within a hazardous area, removing or reducing cabling, cabinets and isolation barriers and, ultimately, saving time and money during installation. According to the manufacturer, DMx combines both protection and condition- monitoring functionality in a single device, making it ideal for use with critical machinery such as gas turbines, generator sets, motors, pumps and compressors in a wide range of industries.

Vibration Institute Certification
Certification adds credence to any professional skill and acknowledges the capability and motivations of individuals. It provides professional recognition by clients, employers and colleagues. Certification activities have increased and broadened the knowledge and skills of vibration analysts. A certifying body—which assesses the capability and knowledge of individuals against a published body of knowledge—must achieve a recognized credibility.
The Vibration Institute certification program, initiated in 1993, is based on ISO 18436.
- Part 1 defines how a vibration certification program is administered.
- Part 2 contains a body of knowledge divided into skill categories.
To be credible, the certifying body must have a scheme committee comprised of technical experts to develop exams that fairly assess the knowledge and skills of candidates. In order to assure the public that a certification program is credible, a certifying body should be accredited. The Vibration Institute is accredited by the American National Standards Institute to ISO/IEC 17024—which pertains to accreditation of personnel certification bodies. Rules for operation of a credible certification program require a certifying body to be a financially viable, transparent organization; to have any training totally separated from the certification process; and to have both statistically and cognitively based examinations related to a credible body of knowledge.

Industry’s Partner In The Vibration Trenches Since 1918
VSC has been helping prevent machinery failures and unnecessary repairs since 1918. The company notes that it balanced Thomas Edison’s turbines and generators and Henry Ford’s Model T crank shafts.
Today, using state-of-the-art instrumentation (now developed in-house), it offers 24-hour machinery diagnostics, balancing and alignment, at your site or in the VSC Balancing Center. Service personnel are accustomed to evaluating rotating equipment in both land-based and marine applications. The Balancing Center is able to accommodate rotors weighing up to 20,000 lbs. in-house and up to 400,000 lbs. on-site. A complete line of condition-monitoring products and training services also are offered.

Meggitt Sensing Systems, makers of Wilcoxon vibration sensors and sensor networks, is offering three new accelerometers with M12 connectors to its line. The M12 connector makes it easy to implement vibration monitoring where existing infrastructure is already built around the M12 standard, such as in the process industries. The new products are hermetically sealed using a fused glass-to-metal connector, feature all welded construction and are rated for temperatures up to 120 C.

First-Alert Wireless Vibration Sensors
IMI’s Echo™ Wireless Vibration Sensors can safely “look” at a machine’s health several times a day and provide data to existing vibration- or plant-monitoring systems. The Echo operates in the 902 to 928 MHz unlicensed ISM band, has a -155 dBm noise floor and -145 dBm sensitivity. It can detect RF signal levels down to a millionth of a billionth of a milliwatt. Actual field-testing has achieved signal transmission distances of 1/3 mile through buildings. Outdoor transmission has been measured in miles.
