An Overview of Vibration Transducers

What are vibration transducers? Vibration transducers used for machinery evaluations are devices that measure displacement of a shaft or motion of a structure and convert this motion into electrical signals. There are three basic types of vibration transducers: Accelerometers  Velocity transducers  Non-contact Displacement transducers Features of vibration transducers Of these three types of transducers, both…

How Vibration is Measured (Cont.): Vibration Level Charts, ISO Values, and More

In Part 1 of How Vibration is Measured, we discussed how equipment vibration is measured.  An accelerometer mounted to a machine bearing vibrates.  This vibration in the accelerometer produces a voltage.  The amount of movement of the accelerometer determines the amount of voltage, and the severity.  The frequency of the voltage (how many times per…

How Vibration is Measured: A Look at Sine Waves, FFT, and More

Machinery vibration continues is an indispensable tool for knowing the condition of machine components.  While analyzing vibration can sometimes be complex, understanding the basics of what a vibration signal is can simplify the process. Taking a vibration measurement on equipment typically requires two components – an accelerometer, and a device, such as a vibration analyzer…
