High-g triaxial piezoresistive shock accelerometers up to 60,000 g
Selectable ranges per axis are available by special request. For each axis, the MEMS sensor is etched from a single chip of silicon, which includes the inertial mass and strain gages arranged in a patented four-active-arm Wheatstone bridge circuit configuration. This unique construction allows for a sensor with high resonance frequency, low output impedance, ruggedness 3x to over-range, and zero damping for minimal phase shift over its useful frequency range. Because the units are undamped, they can also accurately respond to fast rise times and short duration shock motion.
With a frequency response extending down to DC (steady state), the 7274 series is also ideal for measuring long duration transient shocks while integrating critical acceleration data for velocity and displacement. In addition, the sensors feature a robust eight-conductor cable that is expressly designed to repeatedly withstand high-g shock acceleration inputs. Units also feature simple screw mount installation with factory controlled and tested cross-axis performance, making them more cost-effective and easier to install than three similar-type single axis accelerometers with a mounting block.
