Features and Benefits
Precision Alignment
Each Axis of the 34100A is precision aligned to minimize errors due to axis
misalignment or transverse sensitivity.
High Accuracy and Linearity over Wide Temperature Range
The voltage output for each axis of the 34100A is directly proportional to
the acceleration along that axis. Each DC-coupled output is fully scaled,
referenced, and temperature compensated. A force-balanced design
improves accuracy by minimizing variations due to temperature and aging
effects, resulting in a sensor that is more stable over temperature than
piezoelectric or piezoresistive devices.
Calibration Certificate
Each 34100A can be supplied with an optional calibration certificate listing
gain, offset, and on-axis and transverse alignment parameters needed to
ensure rapid and efficient system implementation. The alignment data can
be used to compensate the measured values to achieve an even higher
level of sensor accuracy.
Self-Test on Digital Command
A TTL-compatible self-test input causes a simulated acceleration to be
injected into all three sensors to verify channel integrity.
Small Size
Complete conditioned tri-axial accelerometer in less than a cubic inch.
Single +5 Volt Supply
A regulated +5 volt power supply is all that is required to measure
accelerations on all three axes.
Suitable for Harsh Environments
The 34100A is robust and can be used in harsh environments. The unit will
survive 500 g powered and 2000 g unpowered.

Precisely Measure
Real-World Accelerations
The Summit Instruments 34100A
accelerometer has each mutually orthogonal
axis precisely aligned within 1/2 degree of
the theoretical ideal. This provides the
accuracy required by most linear and
angular measurement applications without
any compensation. Critical applications
requiring higher accuracy can use the
alignment data provided on the optional
calibration certificate to compensate for any
small residual error.
A +5 volt regulated power supply is all that
is required to measure ±10 g, ±15 g, ±20 g,
±25 g, ±30 g, ±50 g, or ±75 g accelerations
on each of three axes. Each axial sensor
has been tested over the -40 to +85°C
temperature range. Each axis has a nominal
full scale output swing of ±2 volts. The
zero g output level is nominally +2.5 volts.
Precise values for each axis are available on
an optional calibration certificate. Custom
versions of the 34100A can be provided for
applications which require different ranges
and/or bandwidths.
