Meggitt Sensing Systems’ Endevco model 7251A series is a family of small, lightweight, hermetically sealed piezoelectric accelerometers with integral electronics. The centrally located thru-bolt mounting hole of this series provides both 360° cable and connector orientation, allowing the sensor to offer a flat-mounting surface even when not fully perpendicular. The mounting provides for ease of use in a variety of automotive applications such as component durability and heavy-equipment testing as well as aerospace applications. Available in standard model sensitivity ranges from 500 to 10 mV/g with optional high temperature to 150°C (302°F) and transducer electronic data sheet (TEDS) versions, the design of the 7251A series incorporates an annular shear piezoelectric sensing element along with an internal hybrid signal conditioner within a two-wire system. Its lightweight construction of 10.5 g (0.37 oz) effectively minimizes mass loading effects.
