Reciprocating Compressors Reciprocating Compressors Reciprocating Compressors are utilized in all manufacturing industries. Because these machines are capable of providing high pressure along with variable loading, 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 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 SKF Bearing Greases and their Applications Courtesy of SKF Maintenance Products      LGMT 2 SKF general purpose industrial and automotive bearing grease 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 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 Eccentricity Eccentricity Shaft Eccentricity plays a very important role as part of a Turbine Supervisory Instrumentation (TSI) System on large steam turbines and should be included in retro-fit p Eddy Current (Proximity Probe) Transducer Installation: Part 1 Radial Vibration Eddy Current (Proximity Probe) Transducer Installation: Part 1 Radial Vibration Eddy Current Transducers (Proximity Probes) are the vibration transducer of choice when installing vibrat Fault Detection / OK Circuits Fault Detection / OK Circuits Over the years, two methods of vibration transducer fault detection have become prominent: OK Circuits and Fault Detection Circuits. The objective of b Reverse Dial Alignment Reverse Dial Alignment Mis-alignment can be the most usual cause for unacceptable operation and high vibration levels. New facilities or new equipment installations are often plagued Thrust Position Thrust Position Thrust Position Monitoring was one of the earliest applications for Eddy Current Transducers. When utilized for this application, it is one of the most important componen Turbine Supervisory Instrumentation: Shell or Case Expansion Turbine Supervisory Instrumentation: Shell or Case Expansion Shell or Case Expansion is a very important measurement as part of a Turbine Supervisory Instrumentation (TSI) System for la Valve Expansion Valve Expansion Valve position measurements are an important aspect of a complete Turbine Supervisory Instrumentation system. Typically, the Main Steam Control (or Throttle) Valve is Velocity Transducer Installation Velocity Transducer Installation The velocity pickup is a very popular transducer or sensor for monitoring the vibration of rotating machinery.
