Endevco® Model 2222C Super Miniature Piezoelectric Accelerometer - 1

Model 2222C Piezoelectric accelerometer Features • 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.
