The Endevco Model 7240B is a miniature, light weight
piezoelectric accelerometer designed specifically for
high frequency vibration measurement on structures and
objects. Its unique sensor design allows high seismic
resonance and ruggedness in the same package. The unit
is hermetically sealed against environmental contamination,
and its light weight (4.8 gm) effectively minimizes mass
loading effects. The accelerometer is a self-generating
device that requires no external power source for operation.
The Model 7240B 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. Signal ground is
connected to the outer case of the unit. When used with
one of the supplied isolated mounting studs, the accelerometer
is electrically isolated form ground. A specifically designed
low-noise coaxial cable is supplied for error-free operation.
Endevco Signal Conditioner Models 133, 2775A or CCAS™
are recommended for use with this high impedance accelerometer.
