Meggitt Sensing Systems has introduced the Endevco model 7284 series, a family of lightly damped, high-g, triaxial, piezoresistive shock accelerometers designed for weapons testing, high-g data recorders, missile fuses and other extreme-g applications. According to the company, the rugged sensors, available in 20,000 g and 60,000 g ranges, provide survivability and low power consumption in these applications.
The 7284 series is the triaxial version of the company's single-axis 7280A series. It shares the same footprint, bolt pattern and 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. Because units are only lightly damped, they still accurately respond to fast rise times and short duration shock motion, the company says.
