The Endevco® model 7284 series is a family of rugged, lightly
damped, piezoresistive triaxial accelerometers designed for highacceleration shock measurements in three mutually perpendicular
axes. This family uses three sensors that are mounted in a triaxial
arrangement inside a single housing, which shares the same
footprint and bolt pattern as the Endevco® model 7280A lightly
damped single-axis accelerometer. The accelerometer boasts a
robust eight conductor cable that can repeatedly withstand the
high-g shock environment.

20 000 and 60 000 g ranges
Lightly damped for exceptional survivability
Low power consumption
Minimal zero shift after shock

The model 7284 uses a unique micro-machined, piezoresistive
sensor with light gas damping to attenuate resonant amplitudes,
and mechanical stops to reduce breakage under overload
conditions. The monolithic sensor incorporates the latest MEMS
technology for ruggedness, stability and reliability.
U.S. patent number 6,988,412 applies to this unit.
