Product
Overview
The
IMU6-1
MEMS
Inertial
Measurement
Unit
provides
precision
measurement
of
three-axis
angular
rate,
acceleration,
and
inclination
angle.
Custom
configurations
are
available
to
meet
specific
measurement
accuracy
and
range
requirements.

(including
temperature
compensation,
installation
misalignment
angle
compensation,
and
nonlinear
compensation),
the
processed
data
is
output
via
RS-422
serial
port
using
a
standardized
communication
protocol.
