 The Endevco Model 7269 is a miniature, triaxial accelerometer
for measuring three orthogonal axes simultaneously. Because
of the small size and light weight, the 7269 is ideal
for biomechanics research such as the study of head injuries.
Applications include testing of ejection seats, heads-up
displays and sports helmets. Weighing only 0.4 grams,
they can be used for making measurements on light structures
with a minimum of mass loading. The extremely small size
allows for installation in hard to access areas or on
small electronic assemblies.
The 7269 utilizes three advanced micromachined sensors
designed for ruggedness, high output and a high resonance
frequency. The sensors include integral mechanical stops
and internal diodes are provided for electrostatic discharge
protection. Each accelerometer has a full scale output
of 400 mV using 10 VDC excitation. The accelerometer has
minimum damping, thereby producing negligible phase shift
over the specified frequency range. The frequency response
extends down to DC (steady state) acceleration, making
it ideal for measuring long duration transient shocks.
The Endevco Model 136 Three-Channel System, Model 4430A
or OASIS 2000 Computer Controlled System are recommended
as signal conditioner and power supply.
