Meggitt Sensing Systems has introduced the Endevco model 7274 series, a family of undamped, high-g triaxial piezoresistive shock accelerometers, designed for high-acceleration shock measurements across three mutually perpendicular axes. The Endevco model 7274 series is the triaxial version of the company’s single-axis 7270A series, sharing the same footprint, bolt pattern and sensing system.
Available in four ranges of 2000 g; 6000 g; 20,000 g; and 60,000 g, the design of the model 7274 series incorporates three sensors mounted in a triaxial arrangement within a single housing. Selectable ranges per axis are available by special request. For each axis, the micro-electro-mechanical systems sensor is sculptured from a single chip of silicon, which includes the inertial mass and strain gages arranged in a four-active-arm Wheatstone bridge circuit configuration.
With a frequency response extending down to dc (steady state), the 7274 series can also be used for measuring long-duration transient shocks while integrating acceleration data for velocity and displacement. In addition, sensors feature an eight-conductor cable that is expressly designed to repeatedly withstand high-g shock acceleration inputs.
