Piezoelectric Accelerometer Features 10mV/g Sensitivity

Meggitt Sensing Systems has launched the Endevco model 2250A, an extremely small, adhesive mounted ISOTRON piezoelectric accelerometer with integral electronics, designed to support high-reliability vibration measurements of mini-structures and smaller objects within aerospace, automotive, electronic product and product life cycle testing (HALT/HASS/ESS) applications.

Offered with a sensitivity of 10mV/g, the model 2250A features high resonance frequency and wide bandwidth, with a lightweight (0.4gm) design that effectively eliminates mass loading effects. The accelerometer incorporates Meggitt’s own Piezite type P-8 crystal element, operating in annular shear mode, which exhibits excellent output sensitivity stability over time. The accelerometer also incorporates an internal hybrid signal conditioner within 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 field-replaceable miniature coaxial cable is supplied with the 2250A-10, as well as a special tool to ensure proper removal of the accelerometer (model 31275) from its adhesive mounting surface.
