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 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 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 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 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 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 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 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. 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 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 Turbine Supervisory Instrumentation Improve Reliability and Performance with a TSI from STI Vibration Monitoring STI’s Turbine Supervisory Instrumentation (TSI) Systems provide cont 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 Velocity Transducer Installation Velocity Transducer Installation The velocity pickup is a very popular transducer or sensor for monitoring the vibration of rotating machinery.
