The Model 7269 is a miniature triaxial accelerometer that is ideal for biomechanics research, studies of head injuries, testing of sport helmets, heads-up displays and ejection seats.
The Model 7269 is a miniature triaxial accelerometer that is ideal for biomechanics research, studies of head injuries, testing of sport helmets, heads-up displays and ejection seats.
The device weighs only 0.4g, allowing for measurements on light structures with a minimum of mass loading.
Its extremely small size facilitates installation in hard to access areas or on small electronic assemblies.
Using three micromachined sensors, the rugged Model 7269 offers exceptional output and high resonance frequency.
This sensor includes integral mechanical stops and internal diodes for electrostatic discharge protection.
The accelerometer has a full scale output of 400mV using 10V DC excitation.
Minimum damping produces negligible phase shift over the specified frequency range.
The frequency response extends down to DC (steady state) acceleration, making the Model 7269 ideal for measuring long-duration transient shocks.
Endevco's Model 4430A or Oasis 2000 computer-controlled system are recommended as signal conditioner and power supply.
