Tri-Axial Accelerometers connect directly to BIOPAC hardware and
require no additional amplification. They provide three outputs, each
simultaneously measuring acceleration 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.
• ±5 g accelerometers are optimal for measuring accelerations
when performing slow movements, such as walking.
• ±50 g accelerometers are optimal for measuring quick
movements, such as swinging a tennis racket.
The transducers can be used on any part of the body or attached to external equipment. The pliable and
unobtrusive design conforms readily to body contours and includes a Velcro strap for easy attachment. The
frequency response extends from DC to 500 Hz. The accelerometers are extremely accurate and can easily be
calibrated by simply changing their orientation in three-dimensional space, so that gravity (G=1) acts only upon
the desired axis.
MRI Use (TSD109C2): MR Conditional
Condition: Trace metallic parts do not make contact to the subject; must be used with MRI cables provided.
Equipment
• The SS26LB/SS27L accelerometers connect to the MP36/35 Data Acquisition Unit.
• The TSD109 series accelerometers connect to the HLT100C High Level Transducer module.
• The TSD109C2-MRI is intended for MRI use and ships with a longer (10 m) cable, plus an MECMRI-
HLT (2 m) interface cable and filter set (MRIFIF).

Hardware Setup
The accelerometers have three output connectors, one each for the X, Y, and Z axes. Each output connector must
be connected to an MP3X input channel (SS26LB/SS27L,) or to the appropriate HLT100C input channel
(TSD109 series). For example, connect the X-axis to channel 1, Y-axis to channel 2, and Z-axis to channel 3.
