Accelerometer suits crash and flutter testing applications.
Press Release Summary:
Model 7268C miniature piezoresistive accelerometer employs micro-machined sensors with integral mechanical stops. Three-axis unit has minimum damping, thereby producing no phase shift over useful frequency range. Two active arms and two internal precision fixed resistors provide shunt calibration, while internal diodes furnish electrostatic discharge protection. Acceleration ranges are 500 and 2000 g full scale, and operating temperature is 0-150°F.

Miniature Model 7268C Piezoresistive Accelerometer Designed for Crash and Flutter Testing Applications
SAN JUAN CAPISTRANO - January 13, 2003 - Endevco's new Model 7268C is a miniature piezoresistive accelerometer (10 x 10 x 13 mm) that employs advanced micro-machined (MEMS) sensors with integral mechanical stops for ruggedness and years of reliable service. This 3-axis accelerometer is designed for applications that require minimal mass loading, such as crash testing and flutter testing, and meets SAE J211 specifications for anthropomorphic dummy instrumentation. The Model 7268C's broad frequency response extends down to DC (steady state) acceleration, allowing it to measure both long duration transients and short duration shocks.
Based on Endevco's proprietary sensor design, the Model 7268C offers high output and high resonance frequency. The sensor has minimum damping, thereby producing no phase shift over the useful frequency range. An operating temperature of 0°F to +150°F(-18°C to +66°C) ensures high performance even under the harshest testing conditions. Two active arms and two internal precision fixed resistors provide shunt calibration, while internal diodes furnish electrostatic discharge protection. A 12 wire integral cable is also included. The Model 7268C is the replacement for the Model 7268B and is available in two acceleration ranges, 500g or 2000g full scale.
