Tri-axial Accelerometers connect directly to the MP3X unit to provide three outputs, each simultaneously measuring accelerations in the X, Y, and Z directions, requiring no additional amplification. They are the same size and can be used on any part of the body or external equipment. The pliable and unobtrusive design conforms readily to body contours. They come with a Velcro strap for easy attachment. The accelerometers have a frequency response which extends from DC to 500 Hz. They are extremely accurate and can be easily calibrated by simply changing the orientation in three dimensional space, so that gravity (G=1) acts only upon the desired axis.
One input channel is required for each output—three input channels are required to measure each axis simultaneously.
SS27L is optimal for measuring quick movements, such as swinging a tennis racket.
SS26LAis optimal for measuring accelerations when performing slow movements, such as walking.
Attachment Guidelines
To prevent cable stress/tugging when the subject moves, which might affect the sensor, tape the cable to the subject.
Tape the cable at a point a few inches from the accelerometer board/sensor (the molded part).
Make a small loop with the cable after the first taping and then tape the cable again.
