Micro-miniature triaxial piezoelectric accelerometer
0.4 pC/g, 10 000 g pk | Model 23 Meggitt Sensing Systems - Measurement Group

Endevco® model 23, the world's smallest triaxial piezoelectric accelerometer, is designed specifically for vibration measurement in three orthogonal axes on small objects such as scaled models, circuit boards, and disk drives. Its light weight, (0.8 gm) without the replaceable coaxial cables, effectively eliminates mass loading. All three low-noise cables exit from a single surface to allow mounting flexibility. The accelerometer is a self-generating device that requires no external power source for operation.

Model 23 features Endevco's Piezite® Type P-8 crystal element, operating in radial shear mode, which exhibits excellent long term output sensitivity stability. Signal ground is isolated from the mounting surface of the unit by a hard anodized surface. Specially designed low-noise coaxial cables are supplied for error-free operation. An accelerometer/cable removal tool is included in the package to ensure proper removal in the field. Endevco signal conditioner models 133, 2775A or Model 4990a computer-controlled system are recommended for use with this high impedance accelerometer.
