256-100

  • Light weight (3.5 gm)
  • Hermetically sealed
  • Milli-g’s resolution
  • Flat to 10 kHz
  • Various vibration and shock measurements on small structures
  • Low cost, modal ready

The Endevco® model 256 is a small piezoelectric accelerometer with integral electronics, designed specifically for making modal and general vibration measurements on small structures. The transducer is designed for adhesive mounting. A dielectric layer isolates the case ground from the mounting surface. The hermetically sealed top connector and welded housing provide long-term reliability even in harsh environments. Its light weight (3.5 gm) effectively minimizes mass loading effects.
The model 256 features Endevco’s unique PIEZITE® type P-8 crystal element, operating in annular shear mode, which exhibits excellent thermal transient stability. This accelerometer uses a built-in low noise microelectronic amplifier which transmits its low impedance voltage output through the same two-conductor cable that supplies the required constant current power. A model suffix indicates output sensitivity in mV/g; i.e., 256-10 features output sensitivity of 10 mV/g.
