Meggitt's Endevco model 7287 low-mass piezoresistive accelerometer is designed for general-purpose shock testing
Meggitt Sensing Systems introduces the Endevco model 7287, a low-mass piezoresistive accelerometer weighing less than one gram, designed for the measurement of long-duration transient shocks.
With a measurement range of 2,000 g, 200 mV full scale output and a resonance frequency of 20,000 Hz, the Endevco model 7287 utilizes a MEMS sensing element incorporating integral mechanical stops and features a small package for minimal mass loading of the test structure. The monolithic sensor design offers a frequency response from DC to 4,000 Hz at ±5%, with non-linearity of <1% and ruggedness to 10,000 g shock. The Endevco model 7287 has also minimum damping, thereby producing no phase shift over the useful frequency range.
