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 Cooling Tower Fans Cooling Tower Fans Cooling Tower Fans have applications in all industries. They remove heat from other materials, usually water. A cooling tower may consist of one cell or many individual cells 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 Journal Bearings Journal Bearings Industrial machinery with high horsepower and high loads, such as steam turbines, centrifugal compressors, pumps and motors, utilize journal bearings as rotor supports. 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, 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 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 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 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 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 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 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 Service Field Service Proper installation is critical to the performance, integrity and credibility of your Vibration Monitoring or Information System. A proper installation is dependent on, qua 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 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 Predictive Maintenance Program (PMP) Predictive Maintenance Program (PMP) A Quality Rotating Machinery Predictive Maintenance (PM) Program for your facility will return your investment many times over.
