Ultrasonic Leak Detection: How Does it Work? Ultrasonic Leak Detection   How does it work??? As the name implies ultrasonic leak detectors detect the ultrasonic sound of a leak. You are probably familiar with Flatness Measurement Application Note Courtesy of Damalini Flatness Flatness measurement is done on for example machine tables, wire parties in paper making machines, flanges (circular planes), machine foundations Dial Indicator Alignment Dial Indicator Alignment Procedure The procedure for doing reverse dial indicator alignment is not a difficult one.  There are several steps which need to be taken for a s Thermography Thermography Courtesy of SKF Maintenance Products Detect hot spots before they cause trouble.   Since the dawn of the industrial age, temperature has been us Lubricants SKF Lubricants The perfect solution for every application  Courtesy of SKF Maintenance Products Even the very best bearing can only show opti Field Application Note: Reverse Dial Alignment Courtesy of STI Vibration Monitoring Inc. www.stiweb.com Misalignment can be the most usual cause for unacceptable operation and high vibration levels. New facilities or new equipm Gardening: Lighting Terminology & Lighting System Comparisons Lumen: This is the basic unit of light. If you could grab a bunch of light in your arms, the term lumen would describe the amount of light that you have. Since this is the description of th Laser Sheave / Pulley Alignment Application Note Large savings to be made with correctly aligned machines A common misunderstanding is that sheave/pulleys are not affected dramatically by misalignments. This assumption has res Mounting & Lubrication Courtesy of SKF Maintenance Products Prevent 16% of premature bearing damage Around 16% of all premature bearing failures are a result of poor fitting or using incorrect mounting techniques. Laser Alignment of Cooling Tower Jack Shaft Application Note Courtesy of Damalini Proper Alignment Will Reduce Your Carbon Footprint! Traditionally, maintenance departments do not sing their own praises. Maybe that should change? In many co Straightness Measurement Application Note Courtesy of Damalini Straightness measurement is done on a large number of applications, for example balks, rolls, machine constructions, transportation lines etc. The basic Acceleration Enveloping Application Enveloping Acceleration envelope measurements are a new introduction to the inventory available to vibration analysts. Although initially it would seem to be most useful for detecting Accelerometer Installation Guide Accelerometer Installation Guide Table of Contents: Section I : Introduction Section II : Mounting Accessories Installation Tools Adhesives and Sealants Accelerometer Transducers and Installation Accelerometer Transducers and Installation Accelerometers have been a popular choice for rotating machinery vibration monitoring. They are a rugged, compact, light weight transducer wi Balancing Balancing Unbalance is a very common source of high vibration that is identified by excessive levels of vibration amplitudes at a frequency that is synchronous with machine speed. Possib Bearing Failure Modes Bearing Failure Modes This application note presents specific failure modes associated with machinery having journal bearings. Signal measurements presented here are time waveforms that Classification of Machines Classification of Machines This application note will provide a basis for selection of the machinery list of a Predictive Maintenance (PM) data collector program. Creating a PM mach Comparing Vibration Readings Comparing Vibration Readings Comparing vibration level readings taken by different types of instruments and transducers can be very confusing and can lead to mistrust of the systems involve Conventions Conventions This application note provides a set of conventions to provide order and meaning to how transducers relate to their mounting and the machine. Motion Towards Vibratio Differential / Rotor Expansion Differential / Rotor Expansion Differential Expansion (DE) and/or Rotor Expansion (RE) are very important measurements usually supplied by the Original Equipment Manufacture (OEM) as part of a
