Piezoresistive
Angular Accelerometer Endevco Model 7302B
The Endevco Model 7302B series of angular accelerometers
are designed to provide accurate measurements of rotational
accelerations. They are available in two ranges to best
suit the intended application. The sensing system consists
of a temperature compensated piezoresistive accelerometer,
uniquely designed to reject cross axis angular and linear
accelerations. The sensor is fluid-damped to optimize
frequency and phase response within a 0° to 250°F (-17°C
to 120°C) temperature range.
Applications for this accelerometer include the measurement
of irregularities in shaft and drive train rotation for
machine and turbine monitoring. In automotive crash studies,
the Model 7302B can be mounted in anthropomorphic test
dummies to measure rotational body accelerations experienced
under impact.
The 7302B series provides a nominal 200 mV full scale
output with 10 VDC excitation voltage.
Endevco Model 136 Three-Channel System, Model 4430A or
OASIS 2000 Computer Controlled System are recommended
as signal conditioner and power supply.
