The TriRate is a complete triaxial angular rate
sensor
based
on
a
surface-micromachining

technology capable of sensing angular motion about
three orthogonal axes. The TriRate provides analog
outputs for angular rate and precision references
about the X, Y, and Z axes. A temperature output is
also provided allowing the implementation of
compensation techniques. Two digital self-test
inputs electromechanically excite each axis to test
proper operation of both sensors and the signal
conditioning circuits.
For pricing information contact MEMSense Sales at
888.668.8743 extension 15 or via email at
sales@memsense.com.
The TriRate is available in a custom SMT package
measuring 0.70 in × 0.70n × 0.40 in.
