Piezoresistive
Accelerometer Endevco Model 7231C-750
The Endevco Model 7231C-750 is a rugged, undamped, medium
g level Piezoresistive Accelerometer designed specifically
for automotive crash test studies. This transducer has
become the FMVSS 208 standard for anthropomorphic dummy
response studies, providing measurements of head, chest,
pelvis and other body accelerations in studies for safer
vehicle and restraint design.
The Model 7231C Piezoresistive Accelerometer utilizes
two active silicon strain gauges and two fixed resistors
(500 Ohm each) arranged in a Wheatstone bridge configuration.
This configuration provides for a low impedance output
of 150 mV full scale with 10 VDC excitation and shunt
calibration capability.
The Model 7231C Piezoresistive Accelerometer utilizes
an anodized aluminum housing and an open connector cover
to allow for solder terminal pins to be accessed. A closed
cover configuration with cable strain relief shielding
the solder pin terminals is available on special order.
This unit is also available with increased performance,
providing for 1% transverse sensitivity ("T" option) and
+/-3% tolerance on sensitivity ("S" Option) on special
order.
Endevco Model 136 Three-Channel System, Model 4430A or
OASIS 2000 Computer-Controlled System are recommended
as signal conditioner and power supply.
Features:
• Rugged, undamped
• Automotive standard
• 750 g full scale
• DC response
