The Endevco Model 7264B 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. Used for
shock testing of light weight systems or structures, the
Model 7264B-2000 accelerometer also meets SAEJ211 specifications
for anthropomorphic dummy instrumentation.
The Model 7264B utilizes an advanced micromachined sensor
which includes integral mechanical stops. This monolithic
sensor offers improved ruggedness, stability and reliability
over previous designs. The Model 7264B 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 transients as well as short
duration shocks.
The Model 7264B offers excellent linearity and a wide
frequency response. Further, this accelerometer offers
table performance over the temperature range of -65°F
to +200°F (-54°C to +93°C) and has a full bridge circuit
with fixed resistors for shunt calibration. This accelerometer
has a full scale output of 400 mV with 10 VDC excitation
(sensitivity of 0.80 mV/g for -500 and 0.20 mV/g for -2000).
It is also available with less than 1% transverse sensitivity
("T" Option) on special order.
Endevco Model 136 Three-Channel System, Model 4430A or
Model 68207 BCAS™ 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
• undamped
