GP Series
The GP Series accelerometers are low
cost, general purpose, linear acceleration and/or vibration sensors available
in ranges of ±4g, ±10g, and ±25g.
Common applications are automotive testing, instrumentation, and
equipment monitoring. The GP Series
sensing element is a silicon micro-machined capacitive beam. The capacitive
beam is held in force balance for full
scale non-linearity of less than 0.2%.
The GP Series offers wide dynamic
r a n g e , h a s e x c e l l e n t f re q u e n c y
response, operates on a single 4.9 to
5.5 VDC power supply, and is easy to
interface to standard data acquisition
systems. The 3-axis version (GP3) can
be specified with an internal regulator
(-R option) for use with a 5.5 to 36 V
unregulated power supply.
The GP Series sensors provide a direct
high-level analog voltage output.
The output requires no external
signal conditioning electronics and
may be directly interfaced to an A/D
or other data acquisition hardware.
Compared to traditional piezoelectric and piezoresistive accelerometer
technologies, the silicon micromachined
sensors offer equivalent performance
at a significantly lower cost.
The GP Series is offered with a standard
5-pin female connector. The highly
flexible, low-mass cable prevents
disruption of the measurement.

Notes

-3dB, DC coupled sensor
Non-linearity is the deviation from a best fit straight line at full scale. Transverse sensitivity is error measured in the primary axis output created
by forces induced in the orthogonal axis. Transverse sensitivity error is primarily due to the effects of misalignment. Zero g drift is specified as the
typical change in 0 g level from its initial value at +25°C to its worst case value at Tmin or Tmax. Specifications subject to change without notice.
