Meggitt Sensing Systems has announced the launch of
Endevco® model 7255A — a miniature,
lightweight piezoelectric accelerometer with integral
electronics. The rugged design and performance
characteristics of this model make it ideal for use in near-field, high shock, and high level mechanical impact testing
applications, where unwanted high frequency signals often
mask critical low level, low frequency data.
Model 7255A incorporates a built-in mechanical filter,
which blocks high frequency energy associated with near-field high shock, and protects the sensing element from
overstress. An internal electronic filter prevents saturation.
The sensor features a two-wire system with integrated
hybrid signal conditioner which transmits a low-impedance
voltage output through the same cable that supplies
required constant current power. Signal ground is
connected to the inner case of the unit, acting as a shield.
Both output and signal ground terminals are electrically
isolated from the mounting surface. For lower level shock
measurements, a high output version is available. Both
versions include internal sensor assembly strain isolation
which reduces strain input due to bending motion on the
mounting surface (often found in high shock events).
