Abstract
An accelerometer comprising a plurality of proof-masses moveable along a measurement axis; a respective spring rigidly attached to each proof-mass, configured to exert an elastic recall on the proof-mass in the measurement axis; and a fixed stop associated with each proof-mass, arranged to intercept the proof-mass when the acceleration in the measurement axis increases by a step. The proof-masses are suspended in series with respect to one another by springs in the measurement axis, the stops being arranged to successively intercept the respective proof-masses for increasing thresholds of acceleration.
