Piezoelectric accelerometer
Features

Description

• NEW! 2222C-R available as replacement sensor
• Industry standard
• Light weight (0.5 gm)
• Adhesive mounting
• Ground isolated
• Small structure vibration measurement

The Endevco® model 2222C is the world’s most popular
miniature piezoelectric accelerometer for vibration
measurement on mini-structures and small objects.
Its light weight (0.5 gm without the low-noise replaceable
cable) effectively minimizes mass loading. The
accelerometer is a self-generating device that requires
no external power source for operation.
The model 2222C features Endevco’s Piezite® type P-8
crystal element operating in the radial shear mode.
This sensor exhibits excellent output sensitivity stability
over time. Signal ground is isolated from the mounting
surface of the unit by a hard anodized surface. A specially
designed low noise coaxial cable is supplied for error-free
operation. Unit and cable removal tools are included in the
package to ensure proper removal in the field.
Endevco signal conditioner models 133, 2775B, 2771, 6634C or Oasis 2000 (4990A-X
with cards 428 and/or 433) computer- controlled system are recommended for use
with this high impedance accelerometer.
