Endevco Model 7284 Triaxial High-G Shock Accelerometers

Meggitt Sensing Systems introduced the Endevco model 7284 series, a family of lightly damped, high-g triaxial piezoresistive shock accelerometers, designed to support weapons testing, high-g data recorders, missile fuzes and other extreme-g applications. According to the company, the rugged sensors, available in 20,000 g and 60,000 g ranges, offer superior survivability and low power consumption.

The new series is the triaxial version of the company’s single-axis 7280A series, sharing the same footprint, bolt pattern and highly survivable sensing system, while making high-g shock measurements across three mutually perpendicular axes. The design of the model 7284 incorporates three sensors mounted in a triaxial arrangement within a single housing. Each axis features a unique piezoresistive MEMS sensor with light gas damping to attenuate resonant amplitudes and prevent breakage in overload conditions.

With a frequency response extending down to dc (steady state), the 7284 series can measure long duration transient shocks. Simple screw mount installation with factory controlled and tested cross-axis performance makes the new model easier and more cost effective to install than three single-axis accelerometers with a mounting block, the company says. The sensor features an eight-conductor cable designed to repeatedly withstand high-g shock acceleration inputs. Input voltage of 5V and cable length of 48 inches are standard.
