The 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 stand-alone, 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.
