DESCRIPTION
The Model 2422 triaxial accelerometer module combines three orthogonally
mounted model 1210 integrated accelerometers in a rugged case for measuring
accelerations in commercial/industrial environments. It is tailored for zero to
medium frequency instrumentation applications. The anodized aluminum case
is epoxy sealed and is easily mounted via two #8 (or M4) screws. It is relatively
insensitive to temperature changes and gradients. An optional initial calibration
sheet (2422-CAL) and periodic calibration checking are also available.
OPERATION
The Model 2422 produces three differential analog
output voltage pairs (AON & AOP) which vary with
acceleration as shown in the figure (at right). The
outputs can be used in differential mode or single
ended, referenced to halfway between VDD and GND.
The output scale factor is ratiometric to the applied
VDD
voltage and at zero acceleration, both AON & AOP
are equal to halfway between VDD and GND. The "Z"
axis is perpendicular to the bottom of the package,
with positive acceleration defined as a force pushing
on the bottom of the package. The "X" and "Y" axis
directions are marked on the cover with positive
acceleration defined as acceleration in the direction
of the axis arrow.
