Real -World Rates
Features and Benefits
High Accuracy and Linearity over Wide Temperature Range
The voltage output for each axis of the 31206B is directly proportional to the
rotational rate along that axis. Each DC-coupled output is fully scaled,
referenced, and temperature compensated.
Calibration Certificate
Each 31206B is supplied with a calibration certificate listing sensitivity and
offset needed to ensure rapid and efficient system implementation.
Self-Test on Digital Command
A TTL-compatible self-test input causes a simulated rotational rate to be
injected into all three sensors to verify channel integrity.
Small Size
Complete conditioned triaxial rate gyro 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
rotational rates on all axes.
Suitable for Harsh Environments
The 31206B is robust and can be used in harsh environments. The unit will
survive 2000 g powered and unpowered.
Three Year Warranty
Measurement Specialties 31206B Triaxial Rate Gyros are covered by a three
year return to factory warranty.
31206B Analog Rate Gyro
precisionsensors.meas-spec.com Measurement Specialties’ 31206B
Triaxial Rate Gyro is capable of
sensing angular rate around three
orthogonal axes. Fully temperature
compensated analog outputs are
available for the X, Y and Z axes.
Choose the range option best suited
for your application to measure ±50°/
sec, ±150°/sec, ±300°/sec, and ±600°/sec
rotational rates 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 Volts. The zero rate output level is
nominally +2.5 volts. Precise values for
each axis are available on the included
calibration certificate. Custom versions
of the 31206B can be provided for
applications which require different
ranges and/or bandwidths.
