Piezoelectric
Accelerometer Endevco Model 7703A-50-100
The Endevco Model 7703A-XXX ISOSHEAR piezoelectric accelerometer
is designed for general vibration measurement on structures
and objects. The ISOSHEAR design is extremely stable and
insensitive to such environmental inputs as base bending
and thermal transients. This line of accelerometers has
been tested in a radiation environment up to 108
rads. They are also capable of 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 7703A-XXX features Endevco's Piezite® Type
P-8 crystal element, operating in shear mode. This device
exhibits low base strain sensitivity, high resonance frequency
and excellent output stability over time. Signal ground
is isolated from the outer case of the unit. A low-noise
coaxial cable is required for error-free operation. The
model number suffix indicates acceleration sensitivity
in pC/g; i.e., 7703A-100 features output sensitivity of
100 pC/g.
Endevco Signal Conditioner Models 133, 2775A or OASIS
2000 Computer-Controller System are recommended for use
with this high impedance accelerometer.
Features:
• Temperature compensated to +288°C
• Hermetically sealed
• Side connector, 5/8" Hex
• Ground isolated
• General vibration measurements
