Piezoresistive accelerometers

  • 19-Oct-2011 02:54 EDT


The Endevco model 7264C series from Meggitt Sensing Systems is a low-mass piezoresistive shock accelerometer family. Featuring a frequency response extending down to dc (steady state), the series is designed to measure the long duration transient shocks associated with automotive crash testing, anthropomorphic device testing, automotive and aircraft seat belt testing, and other legislative and safety applications in which minimal mass loading and a broad frequency response are absolute requirements. Endevco’s 7264C series features an advanced monolithic MEMS sensor design with integral mechanical stops for ruggedness, stability, and reliability, incorporating a full bridge circuit with fixed resistors for shunt calibration. With a small footprint and 1.4 g (0.049 oz) total mass, the series meets both SAE J211 impact testing and SAE J2570 anthropomorphic testing standards.
