The Key to Successful Machinery Protection

Vibration analysis and monitoring for machinery protection continues to be a rapidly growing field. Whether to use acceleration, velocity, or displacement often places the user in a quandary. So does the choice of vibration sensors. These subjects are discussed in a clear, easy to read manner, with specific examples to illustrate the selections. The intent of the paper is to remove ``guesswork´´ in the selection of sensors and vibration modes. A discussion of the economic justification for vibration is also included.
