 The Endevco Model 7270AM6 series of piezoresistive accelerometers
are rugged units with built-in mechanical filters designed
for shock measurements. The mechanical filter assembly
is designed to mitigate the high frequency content of
a shock pulse in order to protect the accelerometer sensor
from high g, high frequency inputs that would otherwise
exceed the overrange limits. The Model 7270A-XXM6 is available
in ranges of 6,000 or 60,000 g full scale.
Developed by Sandia National Laboratories, the mechanical
isolator consists of an aluminum housing lined with two
layers of elastomer filter that cushions the Model 7270A
Piezoresistive Accelerometer. With the elastomer on both
sides of the accelerometer, the response is the same to
both positive and negative accelerations. The mechanical
filter used in the Model 7270A-XXM6 features a damped
output with a linear phase shift. The unit is usable over
the frequency range from DC to 10 kHz for the temperature
range of -30°F to +150°F (-34°C to +66°C).
The Endevco Model 136 Three-Channel Signal Conditioner,
OASIS 2000 Computer Controlled System or Model 4430A Bridge
Signal Conditioner are recommended as signal conditioner
and power supply.
