Smart Sensor (SS) electrodes and transducers connect to the TEL100M-C amplifier/transmitter and can generally record biopotentials and other signals for up to 24 hours. The Tri-Axial Accelerometers are high level output transducers that provide three outputs, simultaneously measuring acceleration along the X, Y and Z axes. The SS26 is optimal for measuring accelerations when performing slow movements, such as walking and hand tremor. The SS27 is more suitable for quick movements, such as swinging a tennis racket. The transducers are the same size and can be used on any part of the body or attached to external equipment. The pliable and unobtrusive design conforms readily to body contours. They come with a Velcro® strap for easy attachment.
The accelerometers’ frequency response extends from DC to 500Hz. They are extremely accurate and can easily be checked for calibration by simply changing their orientation in three-dimensional space, so that gravity (G=1) acts only upon the desired axis.
Specifications mirror the TSD109F transducer.
