High-g triaxial piezoresistive shock accelerometers available

Endevco high-g triaxial piezoresistive shock accelerometer.

Meggitt Sensing Systems, San Juan Capistrano, Calif., has introduced the Endevco® model 7274 series, a family of high-g triaxial piezoresistive shock accelerometers designed for high-acceleration shock measurements across three mutually perpendicular axes, the company announced in a news release issued Dec. 20.

The Endevco® model 7274 series is the triaxial version of the company’s popular single-axis 7270A series, sharing the same footprint, bolt pattern and highly efficient sensing system.

This product family offers 20 years of field-proven pedigree across thousands of installations. Available in four unique ranges of 2000 g, 6000 g, 20,000 g and 60,000 g, the robust design of the model 7274 series incorporates three sensors mounted in a triaxial arrangement within a single housing.

For each axis, the MEMS sensor is made 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.
