Wireless Vibration Measurement


wireless synchronous acceleration measurement
wireless synchronous vibration measurement
wireless condition monitoring

Wireless vibration or acceleration measurement can easily be done by the use of the TEDIASENS SN-I sensor node. TEDIASENS SN-I is completely wireless by the means of embedded 3D industrial acceleration sensors which allow multiple measurement applications especially in the field of acceleration, vibration, mechanical oscillation and modal analysis. With its small mechanical dimensions (40 x 40 x 82 mm³) and its high measurement accuracy of 1 mg (peak-peak) in the bandwidth from DC or 1 Hz to 8 kHz, it is a perfect cable replacement.
