Endevco 2250A Highlights
The Endevco® model's 2250A/AM1 are extremely small, adhesive mounting piezoelectric accelerometers with integral electronics, designed specifically for measuring vibration on mini-structures and small objects. These accelerometers offer high resonance frequency and wide bandwidth, their lightweight (0.4 gm) effectively eliminates mass loading effects. A field-replaceable miniature cable is supplied with the 2250A-10, and small gage, lightweight hook-up wires are supplied with the 2250AM1-10.
Models 2250A/AM1 feature Endevco's Piezite® type P-8 crystal element, operating in annular shear mode, which exhibits excellent output sensitivity stability over time. These accelerometers incorporate an internal hybrid signal conditioner in a two-wire system, which transmits its low impedance voltage output through the same cable that supplies the constant current power. Signal ground is isolated from the mounting surface by a ceramic mounting base. A tool is included in the package to ensure proper removal of the accelerometer from its mounting surface.
