Accelerometry

Accelerometry is the field of metrology that deals with the quantity "acceleration".

It brings together all the knowledge and techniques related to :

• instrumentation ;

• calibration ;

• signal processing,

• specific to the measurement of this quantity.

The legal unit of acceleration is the meter per second squared (m/s²).

Accelerometer and accelerometer chain

An accelerometer is a sensor directly subjected to the action of the measurand acceleration. It converts this mechanical quantity into a quantity that can be measured or recorded (electrical quantity).

Note: a sensor may include auxiliary equipment to amplify, provide a power supply, the necessary circuit elements, and indicator or record...
