Measuring Vibration with Accelerometers - NI

Jul 15, 2020· 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.

Compaction

Compaction is a process that brings about an increase in soil density or unit weight, accompanied by a decrease in air volume.There is usually no change in water content.The degree of compaction is measured by dry unit weight and depends on the water content and compactive effort (weight of hammer, number of impacts, weight of roller, number of passes).
