Piezoresistive Accelerometers

for shock testing

Meggitt Sensing Systems - Measurement Group

Meggitt Sensing Systems introduces the Endevco model 7287, a small footprint, very low mass piezoresistive accelerometer weighing less than one gram. This piezoresistive accelerometer is designed for the measurement of long duration transient shocks, such as those found in product and packaging drop testing, shipping container shock testing, jack hammer testing and high-g destructive testing applications. With a measurement range of 2,000 g, 200 mV full scale output and a high resonance frequency of more than 20,000 Hz, the accelerometer utilizes a MEMS sensing element incorporating integral mechanical stops and features a small, lightweight, easy-to-mount package for minimal mass loading of the test structure. Its monolithic design offers ruggedness, stability and reliability with broad frequency response, with non-linearity and ruggedness to 10,000 g shock.
