 The Endevco Model 7701A-XXX stud mounted, ISOSHEAR piezoelectric
accelerometer is designed for general vibration measurement
on structures and objects. The ISOSHEAR design is extremely
stable and virtually insensitive to such environmental
inputs as base bending and thermal transients. This line
of accelerometers has been tested in a radiation environment
up to 1E8 rads without performance degradation, and they
are also capable of accurate vibration measurement up
to +550°F (+288°C). These units are hermetically sealed
against external contamination. The accelerometer is a
self-generating device that requires no external power
source for operation.
The Model 7701A-XXX features Endevco's Piezite® Type
P-8 crystal element, operating in shear mode, which exhibits
low base strain sensitivity, high resonance frequency
and excellent output stability over time. Signal ground
is connected to the outer case of the unit. When used
with an isolated mounting stud, the accelerometer is electrically
isolated from ground. The accelerometer features a 10-32
side-connector. A low-noise coaxial cable is supplied
for error-free operation. The model number suffix indicates
acceleration sensitivity in pC/g; i.e., 7701A-100 features
output sensitivity of 100 pC/g.
Endevco Signal Conditioner Models 133, 2775A or CCAS™
are recommended for use with this high impedance accelerometer.
