How an Accelerometer Works. Accelerometers are electromechanical devices that sense either static or dynamic forces of acceleration. Static forces include gravity, while dynamic forces can include vibrations and movement. Accelerometers can measure acceleration on one, two, or three axes.
If the motion transducer in the seismic instrument measures the displacement of the mass relative to the base, the output of the transducer is proportional to the acceleration of the transducer base for a specific frequency range and the device is called an accelerometer.
