GLOSSARY (for vibration purposes)

Piezoelectric A material in which electrical properties change when subjected to

force.

Process Measurements Variables such as temperature, pressure, speed and

flow used to assess internal conditions of efficiency.

Radial Direction perpendicular to the shaft centerline.
Repeatability A measure of the deviation between successive measurements made

under the same conditions.

RMS Peak Vibration x .707. ( in/s or mm/s)

Rolling Element Bearing A bearing consisting of balls or rollers operating between

fixed and rotating races.

Route A sequence of measurements arranged for convenience

during acquisition.

Sensitivity Used to describe a transducer’s electrical output for a unit variation

of the mechanical quantity measured.

Stress Force per unit area
Synchronous Frequency components that are an integer multiple of

running speed.

Transducer A system consisting of a sensor and signal conditioner to convert a

physical quantity into an output for display, monitoring
and analysis.

Transmission Path The path from source (excitation) to sensor.
Trending The plot of a variable over time used as an indicator of change.
Velocity A vector quantity of the time rate change of displacement.
