The Endevco Model 2221D is a piezoelectric accelerometer
designed specifically for vibration measurement on small
structures and objects. The unit is epoxy sealed and it
is ideal for use in controlled environment. Its light
weight (12 gm) effectively minimizes mass loading effects.
The accelerometer is a self-generating device that requires
no external power source for operation.
The Model 2221D 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.
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 adhesive mounted if
the application permits.
Endevco Signal Conditioner Models 133, 2775A or CCAS™
are recommended for use with this high impedance accelerometer.
Features:
• Requires no external power
• Annular shear
• Low profile
• Light weight (12 gm)
• High output, 17 pC/g
• 360° Cable orientation
