Piezoresistive Accelerometers Measure Shock

The Endevco model 72 series high-g, SMT piezoresistive accelerometers support a variety of high-reliability acceleration, vibration, and shock measurements. Available with a 20,000 g measurement range and a soon-to-be-released 60 kg version, the components boast a broad frequency response, minimum zero shift post-shock event, and a Class 3 Rating for electrostatic discharge protection. Their low-profile, miniature, hermetically sealed LCC package weighs 0.16g. Other features include a MEMS sensing element with light gas damping to attenuate resonance, mechanical stops to increase ruggedness, and a frequency response extending down to dc (steady state acceleration).
