Glossary

The vibration monitoring industry has specialized jargon that is commonly used when talking about vibration sensors, accelerometers and associated applications. It's important that you understand common terminology to communicate effectively with vibration monitoring, reliability, condition monitoring and process automation professionals. We hope you find our glossary useful to find specialized terms and definitions used across vibration, condition monitoring and predictive maintenance.

 






END POINTS

The outputs at the specified upper and lower limits of the Range.

ENDEVCO

An acronym for ENgineering DEVelopment COmpany. A leader in developing instrumentation for the sensing of physical phenomena.

EQUALIZATION

The process whereby the response of a vibration system is adjusted to a flat or shaped spectrum.

ERROR

The algebraic difference between the indicated value and the true value of the measurand. In a transducer, usually expressed in percent of the full-scale output reading of the transducer.

ERROR BAND

The band of maximum deviations of output values from a specified reference line or curve as a result of causes due to the instrument.

EXCITATION

The external electrical voltage and/or current applied to a transducer for its proper operation. Mechanical excitation is a mechanical input driving force into a structure such as from a hammer, shaker, etc.

EXCITATION, ELECTRICAL

The voltage or current applied to the input terminals of the transducer.
