Precision Transducer for Research Data Acquisition

Tri-axial accelerometer

Request More Info
Accelerometer 5G (uses 3 inputs)
Part #: TSD109C2, TSD109J

Tri-Axial Accelerometers are high level output transducers that provide three outputs, simultaneously measuring acceleration along the X-, Y- and Z-axes. 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.

  • The TSD109C2 (±5 G) is optimal for measuring accelerations when performing slow movements, such as walking and hand tremor.
  • The TSD109J (±200 G) is more suitable for quick movements, such as swinging a tennis racket.

For the same Platform

With a different Platform



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. TSD109 series accelerometers connect directly to the HLT100C High Level Transducer module. For a wireless equivalent, see the BioNomadix Wireless Accelerometer BN-ACCL3.

Attachment Guidelines

ss26lb accelerometer strapTSD109 accelerometers include two Velcro straps for easy attachment to finger (10 cm) or wrist (33 cm); additional straps may be ordered separately in 20, 33, 76, or 137 cm (use part number BN-STRAP-XX).

For other locations, or to prevent cable stress/tugging when the subject moves, which might affect the sensor, the acceleromter can also be taped to the subject. Tape the cable at a point a few inches from the accelerometer board/sensor (the molded part), them make a small loop with the cable after the first taping and then tape the cable again.

MRI applications: Use TSD109C2-MRI.
