Technical Data*
Features and Benefits
High Accuracy and Linearity over Wide Temperature Range
The voltage output for each axis of the 34205A is directly proportional to the
acceleration along that axis. Each DC-coupled output is fully scaled,
referenced, and temperature compensated over the entire -40 to +85°C
temperature range.
CalibrationCertificate
Each 34205A is supplied with a calibration certificate listing sensitivity and
offset, as well as the 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.
Small Size
Complete conditioned triaxial accelerometer in less than a cubic inch.
­ uilt-In Power Supply Regulation
B
Unregulated DC power from +8 to +18 volts is all that is required to measure
accelerations on all axes.
Suitable for Harsh Environments
The 34205A is robust and can be used in harsh environments. The unit is
packaged in a rugged aluminum housing and will survive 5000 g powered or
unpowered.
Warranty
These Measurement Specialties accelerometers come with a three-year
factory warranty.

34205A
accelerometer provides the accuracy
required by most measurement
applications without any compensation.
Critical applications requiring higher
accuracy can use the alignment data
provided on the calibration certificate to
compensate for any small residual error.
Choose the bandwidth and range options
best suited for your application to measure ±5 g, ±10 g, ±20 g, ±25 g, ±30 g,
±40 g, or ±50 g accelerations on each of
three axes.
Each axial sensor has been tested over
the -40 to +85°C temperature range and
has a nominal full scale output swing of
±2.25 volts. The zero g output level is
nominally +2.5 volts. Precise values for
each axis are available on the included
calibration certificate.
