 The Endevco Model 7259A is a miniature, light weight
piezoelectric accelerometer with integral electronics,
designed specifically for high frequency vibration measurement
on structures and objects. Its unique sensor design allows
for high seismic resonance and ruggedness. The unit is
hermetically sealed against environmental contamination,
and its light weight (4.8 gm) effectively minimizes mass
loading effects.
The Model 7259A features Endevco's Piezite® Type P-8
crystal element, operating in annular shear mode, which
exhibits low base strain sensitivity, wide bandwidth and
excellent output stability over time. This accelerometer
incorporates a low noise internal hybrid signal conditioner
in a two-wire system, which transmits its low impedance
voltage output through the same cable that supplies the
required constant current power. Signal ground is connected
to the outer case of the unit which acts as a shield for
its low impedance output. When used with one of the supplied
isolated mounting studs, the accelerometer is electrically
isolated form ground. A specially designed, low-noise
coaxial able is supplied for error-free operation. A model
number suffix indicates acceleration sensitivity in mV/g;
i.e., 7259A-10 features output sensitivity of 10 mV/g.
Endevco Signal Conditioner Models 4416B, 133, 2792B, 2793,
2775A or OASIS 2000 Computer-Controlled System are recommended
for use with this accelerometer.
