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 Monitoring System Users Monitoring System Users Smooth operation of a machine train involves the cooperation of several disciplines which interface with each other and a vibration monitoring system in differing System Response System Response An understanding of how a spring mass system responds to vibratory influences is helpful in understanding, recognizing and solving many problems encountered in vibrati 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 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 Field Wiring Field Wiring There are a number of items to consider when installing a permanently mounted vibration monitoring system. One of the most critical considerations is the selection and insta Turbine Supervisory Instrumentation 1 Turbine Supervisory Instrumentation 1 Specification of a Turbine Supervisory Instrumentation (TSI) system can be an exhausting process when the individual parameters must be specified Lubricants SKF Lubricants The perfect solution for every application  Courtesy of SKF Maintenance Products Even the very best bearing can only show opti CMCP1100 Wiring Diagram Wiring Diagram for CMCP1100 Courtesy of STI Vibration Monitoring Electrical powering requirements Most internally amplified vibration sensors require a constant current DC power source. General 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 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 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?
