The Endevco Model 7264C is a very low mass piezoresistive
accelerometer weighing only 1 gram. This accelerometer
is designed for crash testing, flutter testing, rough
road testing and similar applications that require minimal
mass loading and a broad frequency response. This accelerometer
meets SAEJ211 specifications for anthropomorphic dummy
instrumentation. It is a direct replacement for the Endevco
Model 7264-2000 in that the location of the center of
seismic mass is the same.
The Model 7264C utilizes an advanced micromachined sensor
which includes integral mechanical stops. This monolithic
sensor offers improved ruggedness, stability and reliability
over previous designs. The Model 7264C has minimum damping,
thereby producing no phase shift over the useful frequency
range. With a frequency response extending down to dc
or steady state acceleration, this accelerometer is ideal
for measuring long duration transient shocks.
This accelerometer has a full bridge circuit with fixed
resistors for shunt calibration. Full scale output is
400 mV with 10 VDC excitation. It is also available with
less than 1% transverse sensitivity ("T" Option) and less
than +/-25 mV zero measurand output ("Z" Option).
The Endevco Model 136 DC Differential Voltage Amplifier,
Model 4430A Bridge Conditioner or OASIS 2000 Computer
Controlled System are recommended as signal conditioner
and power supply.
Features:
• Mechanical overtravel stops
• Small size, rugged
• 500 g and 2000 g full scale ranges
• DC response - long duration transients
• Crash and shock testing
