Technical Data*
Features and Benefits
High Accuracy and Linearity over Wide Temperature Range
The voltage output for each axis of the 13208A and 23208A is directly
proportional to the acceleration along that axis. Each DC-coupled output is
fully scaled, referenced, and temperature compensated. Accuracy is
improved 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 13208A and 23208A 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.
Self-Test on Digital Command
A TTL-compatible self-test low input causes a simulated acceleration to be
injected into the sensor(s) to verify channel integrity.
Small Size
Complete conditioned uniaxial or biaxial accelerometer in less than a cubic
inch.
­ uilt-In Power Supply Regulation
B
Unregulated DC power from +8.5 to +36 volts is all that is required to measure
acceleration and temperature. Reverse power voltages of up to -80 V can
be withstood indefinitely. Transients of +80 V for 550 ms compatible with
MIL-STD-704A can be withstood with full operation.
Easy Installation
Built-in terminal block or cable with 9-pin connector makes it easy to wire.
Two through-holes and four tapped holes simplify mounting.
Suitable for Harsh Environments
The 13208A and 23208A are robust and can be used in harsh environments.
The units will survive 4000 g powered or unpowered.
Warranty
These Measurement Specialties accelerometers come with a three-year
factory warranty

precisionsensors.meas-spec.com Simplify Acceleration and
Temperature Measurements
The Measurement Specialties 13208A
and 23208A accelerometers include a
temperature sensor in their small, rugged
package. The small size and built-in
power regulation allow the 13208A and
23208A to fit where other accelerometers
can’t. Choose the bandwidth and range
options best suited for your application to
measure ±250 g or ±500 g accelerations
on one or two axes.
The high repeatability of the builtin temperature sensor allows precise
compensation of temperature effects.
Alignment data provided on the included
calibration certificate can be used to
manually correct transverse sensitivity
and alignment errors, or when extra
precision is required, Option C002,
offset compensation is available.
Tested over the -40 to +85°C temperature
range, the accelerometers have a nominal
full scale output swing of ±2 volts. The
zero g output level is nominally +2.5
volts. Precise values are available on the
included calibration certificate. Custom
versions of the 13208A and 23208A
can be provided for applications which
require different range and/or bandwidth.
