PCB has several shock accelerometer designs that improve measurement of both high-level (e.g., gun launch and penetration events) and pyrotechnic shock. Pyrotechnic shock, often called pyroshock, is a measurement challenge due to its associated high frequency content, which typically excites the resonant frequency of any measuring accelerometer. As a result, the accelerometer can easily be driven nonlinear due to this resonance excitation. In some situations, the frequency environments associated with severe mechanical shock may be so expansive, the acceleration levels so high, or the off-axis inputs so severe that successful measurements simply cannot be obtained.
