Miniature, General Purpose Piezoelectric Accelerometer

 

 

Meggitt Sensing Systems, a Meggitt group division, has announced the global market introduction of 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 10 mV/g, the Endevco® model 2250A features high resonance frequency and wide bandwidth, with a lightweight (0.4 gm) 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.

 

Recommended optional accessories for the Endevco® model 2250A, sold separately, include the model 133 three-channel piezoelectric signal conditioner; the model 4416B low-noise, compact signal conditioner; the model 2775B PE, Isotron® and RCC signal conditioner; or the Oasis 2000 (4990A-X with cards 428 and/or 433) computer controlled system. All Endevco® accelerometers are accompanied by a comprehensive five-year product warranty, with designated quantities of the model 2250A and select accessories available for immediate customer shipment as part of Meggitt’s Endevco® Guaranteed InStock™ program. The model 2250A-10 is also available at specially discounted rates as part of Meggitt’s –R Replacement Sensors program.
