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 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 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 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 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 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 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 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 Frequency Domain Frequency Domain Frequency domain measurements and analysis have become increasingly popular to diagnose a particular machine fault. This measurement mode relies on processing the Machine Classifications Machine Classifications The type of vibration monitoring system to install on a machine train will depend upon how the machine train is used in the plant process. A very important machin Maintenance Methods Maintenance Methods Every facility that produces a consumer product has some requirement for maintenance or upkeep of their machinery. Depending upon the product and, to some extent, the Piping Vibration Piping Vibration Piping vibration can be an annoying problem which can consume unnecessary maintenance activity and can affect pumping system performance and endurance. The system inc 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,
