The Endevco® Model 2223D is a tri-axial piezoelectric accelerometer designed specifically for vibration measurement of three orthogonal axes on small structures and objects. Its light weight (41 gm.) effectively minimizes mass loading. All three individual sensors are isolated from each other and from the mounting surface by a hard anodized isolator. The accelerometer is a self generating device that requires no external power source for operation.
