Tri-axial accelerometer
uses 3 channel inputs
SS26LA-SS27L Tri-Axial
Accelerometers
The Tri-Axial Accelerometers connect directly to the MP3X and
require no additional amplification. They provide three outputs, each
simultaneously measuring accelerations in the X, Y, and Z directions.
They are the same size and can be used on any part of the body or on
external equipment. The pliable and unobtrusive design conforms
readily to body contours. They come with a Velcro
®
strap for easy
attachment.
The
SS26LA
is optimal for measuring accelerations
when performing slow movements, such as walking.
The
SS27L
is optimal for measuring quick movements,
such as swinging a tennis racket.
The accelerometers have a frequency response that extends from DC to 500
Hz. It is extremely accurate and can be
easily checked for calibration by simply changing its orientation in three-dimensional space, so that gravity (G=1)
acts only upon the desired axis. One input channel is required for each output. Accordingly, you will require three
input channels to measure each axis simultaneously.
