Piezoresistive
Accelerometer Endevco Model 7265A/A-HS
The Endevco Model 7265A series, with sensitivity up
to 25 mV/g, is a family of very low mass (6 gram), piezoresistive
accelerometers designed for flutter testing, biomedical
motion studies and similar applications requiring high
sensitivity, good low frequency response and minimum mass
loading.
The Model 7265A series has viscous damping to extend the
useful high frequency range and to reduce the effects
of spurious high frequency excitation. Mechanical stops
prevent damage when the transducer is subjected to overrange
shock. The Model 7265A series utilizes two of Endevco's
Piezite® P-11 silicon gauges and two fixed resistors
in a full-bridge circuit. This configuration provides
a low impedance output of 500 mV full scale with 10 VDC
excitation.
The Model 7265A has a sensitivity of 5 mV/g and a full
scale of 100 g. The Model 7265A-HS (high sensitivity)
has a very high sensitivity of 25 mV/g with a full scale
of 20 g.
Endevco Model 136 Three-Channel System, Model 4430A or
OASIS 2000 Computer Controlled System are recommended
as signal conditioner and power supply.
