TEDIASENS SN-I

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.

Product Types – Wireless, synchronous Vibration and Oscillation Measurement

TEDIASENS SN-I

  • Wireless sensor node with integrated 3-axis accelerometer in 10g and 100g version
  • Extremely powerful: the signals are sampled with a dynamic of 24 bit and a maximum frequency of 13 kHz
  • Measurement accuracy of 2 mg (RMS) from 1 Hz to 8 kHz (-3dB)
  • Battery for 8-9h continuous runtime
  • Live wireless measurement data transmission to a USB access point via WLAN
  • Display, evaluation and storage of measurement data via PC software (TDS GUI)
  • Synchronous measurement data transmission when using several radio nodes at the same time

TEDIASENS SN-I-ECO

Identical to TEDIASENS (above), however:

  • no synchronous measurement data transmission when using several radio nodes at the same time
