A digital accelerometer comprising a linear analog accelerometer and a digitizer. The analog accelerometer includes a housing and conductor means extending outside the housing, and is adapted to produce on the conductor means an analog signal representing linear acceleration along one axis. A casing is positioned against the housing so as to form a substantially enclosed space between the housing and the casing. The digitizer is located within such enclosed space and receives the analog signal and produces a corresponding digital signal. An interface circuit is positioned within the enclosed space for receiving the analog signal and producing a second analog signal that is input to the digitizer. The digital signal produced by the digitizer may be conveyed to a location outside the enclosed space and housing by a flexible strip of insulating material having a plurality of conductive strips embedded therein. In a preferred embodiment, the interface circuit is operative to determine the magnitude of the second analog signal resulting from a particular first analog signal, whereby the dynamic range of the digital accelerometer can be modified by modifying only the interface circuit.
