Vibration isolation - Wikipedia

Vibration isolation is the process of isolating an object, such as a piece of equipment, from the source of vibrations.. Vibration is undesirable in many domains, primarily engineered systems and habitable spaces, and methods have been developed to prevent the transfer of vibration to such systems.

Measuring Vibration with Accelerometers - ni.com

May 24, 2019· Vibration is most commonly measured using a ceramic piezoelectric sensor or accelerometer. An accelerometer is a sensor that measures the dynamic acceleration of a physical device as a voltage. Accelerometers are full-contact transducers typically mounted directly on high-frequency elements, such as rolling-element bearings, gearboxes, or spinning blades.

What is the basic principle of vibration measurement by ... actually originally designed in the 1930s by GE engineers using vacuum tubes), he had a choice between using N-P-N ...

accelerometers, how accelerometers work, vibration sensors

Vibration levels are measured using accelerometers, which, like most powerful engineering tools, provide excellent service as long as the engineer concerned takes a little time to appreciate how they work. Even the best accelerometer will not offer the precision or longevity of which it is capable if poorly installed or maintained.
