 The Endevco Model 2221F piezoelectric accelerometer
is designed specifically for high temperature vibration
measurement on small structures and objects. The unit
is hermetically sealed and it is ideal for use in extreme
environmental conditions. Its light weight (11 gm) effectively
minimizes mass loading effects. The accelerometer is a
self-generating device that requires no external power
source for operation.
The Model 2221F features Endevco's Piezite® Type P-8
crystal element, operating in annular shear mode, which
exhibits excellent output sensitivity stability over time.
Signal ground is connected to the outer case of the unit
and, when used with an isolated mounting screw, the accelerometer
is electrically isolated from ground. A low-noise coaxial
cable is supplied for error-free operation. The transducer
has a centrally located thru bolt, allowing for 360° cable
orientation. The unit may also be adhesively mounted if
the application permits.
Endevco Signal Conditioner Models, 133, 2775A or CCAS™
are recommended for use with this high impedance accelerometer.

• Requires no external power
