Wireless, synchronous Vibration and Oscillation Measurement
TEDIASENS SN-I is a small and specialized version of the TEDIASENS SN-X radio module. “SN” stands for “Sensor Node”. By avoiding cables as well as an internal industrial 3D accelerometer, numerous measurement tasks in the field of vibration and oscillation analysis can be solved without much installation effort. The industrial acceleration sensors have a measurement range of ± 10 g to ± 100 g and a measurement accuracy of 2 mg (RMS) over the bandwidth of DC or 1 Hz to 8 kHz (-3dB). The signals are sampled with a dynamic of 24 bit and a maximum frequency of 13 kHz. Application of SN-I: wireless synchronous vibration measurement, wireless oscillation measurement, acceleration measurement. Impact tests.
