Triaxial piezoelectric accelerometer with integrated electronics
10 /100 mV/g, 15 g | Model 2258A Meggitt Sensing Systems - Measurement Group

Endevco® model 2258A is a small triaxial piezoelectric accelerometer with integral electronics, designed specifically for measuring vibration in three orthogonal axes on small structures. The transducer features three hermetically sealed 10-32 connectors for output connection, and can be screw or adhesive mounted. Its light weight (15 gm) effectively minimizes mass loading effects.

The model 2258A features Endevco's Piezite® type P-8 crystal elements, operating in annular shear mode, which exhibit excellent output sensitivity stability over time. This accelerometer incorporates three standalone, low noise internal hybrid signal conditioners, each operating in a two-wire system. Its low impedance voltage outputs are connected to the same cables that supply the required constant current power. Signal grounds are isolated from each other and the mounting surface. A model number suffix indicates acceleration sensitivity in mV/g; i.e., 2258A-10 features output sensitivity of 10 mV/g.
