I hope you enjoy the January 2007 Ultrawave Technology Report
Allan Rienstra, Editor The Ultrawave Technology Report	Allow me to start by thanking everyone who continued to derive value from our e-Newsletter in 2006. It was a fantastic year that saw our readership increase beyond ten thousand subscriptions; all opt-in requests by you. As we look to grow our online publication in 2007 we will see the popularity and need for ultrasound monitoring continue to grow along with us. As editor of The Ultrawave Technology Report I am committed to keeping you up-to-date on Ultrasound Tips, News, New Equipment, Training Events and other information relevant to PdM practitioners around the globe. Our philosophy is implementation through education. The Ultrawave Technology Report is one more vehicle to help us make that happen. Our theme this year is "Hear More" which is appropriate since that is what SDT Ultrasound Equipment enables us all to do. Hear more beraing failures, hear more leaks, hear more steam trap failures... Anytime or anywhere you see the "Hear More" logo click to learn more or delve deeper into the subject matter. And now, January's issue:
Ultrasound Tip - Advice on acoustic lubrication
Condition based lubrication of roller bearings depend on ultrasound data collection to warn when re-greasing is required. Lube techs re-grease bearings using an ultrasound sensor interfaced to a grease gun. The sensor provides a signal to the ultrasonic data collector giving the tech both an audible and a digital guidance system designed to prevent damage from over-greasing. Some confusion about how much grease is enough still remains a question mark. Some advice: Send lube techs to an ultrasonic training class. Set alarms to re-lubricate at 8-10 dBµV over baselines established by a digital ultrasonic condition monitoring program. For consistency use the same ultrasonic instrument for both condition monitoring and re-lubrication. Preferably, the ultrasonic device should provide digital measurement and listening capabilities. “Listen-only” units are subjective and depend on the hearing capabilities of multiple users. Apply grease slowly while both listening and measuring. Your target is to return the dBµV values back to baseline. Grease… then wait. Don’t hurry at the expense of doing the job correctly. Allow the grease to work into the cage, rollers, and grease cavity. The bearing may initially go quiet, and then loud again as the grease is worked in. The 8-10 dBµV rule works in most instances, however statistics are a poor substitute for common sense. Use these guideline in harmony with you company’s established greasing protocol to arrive at a unique procedure that suites your needs.
Look at the ultrasonic signal in time domain. Bearing was loud with non-sinusoidal peaks. The moment of truth when the grease actually reaches the bearing is both audible and visible. Click Here to request an electronic copy of the sound file associated with this picture.

Leak Surveyor - One Day Training Courses	2007 Schedule
Implementing an ultrasound compressed air leak survey program that is both effective and enduring is a challenge faced by nearly every company that has tried. Standing between success and failure are several roadblocks including time constraint, manpower shortages, conflicting priorities, and the need to prove out the impact the program will have first; often before funds are approved to start the project. This session covers all aspects from implementation and practices to documentation and reporting.	Portland, 02/13 Houston - 03/6 Phoenix - 04/3 Tulsa - 06/5 Atlanta - 06/7 Denver - 07/17

Impacting Energy & The Environment Through Air Leak Management

The first of many 2007 technical papers addresses compressed air and it's impact on both the energy and the environment. Take a look at how a major glass manufacturer implemented compressed air leak management to generate immediate savings in energy and long-term savings for the environment.

Later this year we'll take a look at the other application benefits ultrasound inspection provided for this world leader in flat glass manufacturing.

St. John, New Brunswick 16 New Level 1 Certified Inspectors

The first public Level 1 Training for 2007 was huge with 16 newly certified inspectors in attendance in St. John, New Brunswick. Leading the course was SDT corporate trainers Debra Smith and Gustavo Velasquez.
Congratulations to Kevin Morrell, Ken Keith, Stephen Agnew, Roger Radcliffe, John Edison, Matthew Lewis, Kevin Sampson, Michael Farrar, Craig Singleton, Bradford Hall, Wayne Stevens, Roger Touesnard, Callum MacDonald, Lonnie Breen, William Fiander, and Stephen Shaddick

2007 Level 1 Training Schedule

Achieving Level 1 ultrasound certification status in 2007 should be on the top of your list of priorities if you planning to:

Implement a World Class Ultrasound Program
Kick start your existing program
Optimize asset lubrication using ultrasound technology
Impact energy costs through compressed air leak management
Conduct routine steam trap surveys
Safely monitor electrical switch gear between infrared scans
