What is the difference between an accelerometer and a vibration sensor? ... An accelerometer measures a quality of acceleration, not necessarily vibration. But vibration sensors, which measure a quantity of acceleration and are therefore a type of accelerometer, are by definition accelerometers.

What is an accelerometer in vibration?

An accelerometer is a device that measures the vibration, or acceleration of motion of a structure. The force caused by vibration or a change in motion (acceleration) causes the mass to "squeeze" the piezoelectric material which produces an electrical charge that is proportional to the force exerted upon it.

What is difference between acceleration and vibration?

is that vibration is (physics) any periodic process, especially a rapid linear motion of a body about an equilibrium position while acceleration is (physics) the change of velocity with respect to time (can include deceleration or changing direction).
