Product characteristics

New features

More integrated sensors – All included in the unit

Leading the market, the new DR4 models include more impressive sensors, such as the gyroscope or the magnometer.

  • High-performance primary capacitive triaxial accelerometer up to 40G for acceleration measurements with sampling frequency up to 4,000 Hz.
  • High-performance secondary piezoresistive triaxial accelerometer up to 2,000 G for shock measurements with sampling rates up to 20,000 Hz.
  • In addition to pressure, humidity and temperature sensors, the data logger also includes other powerful sensors:
    • Gyroscope (to measure tilt and speed change in Pitch, Rall and Yaw).
    • Magnetometer.
    • Light (Useful to know if the package or vehicle has been opened. This sensor is capable of capturing the intensity of visible and ultraviolet light at a frequency of 4 Hz. This sensor is not calibrated and is designed for rough relative measurements only) .
    • Microphone (records at the same speed as the other analog channels (up to 20 kHz).

Innovative analyzer software innSoft, developed by Safe Load Testing Technologies

Intuitive and easy-to-use software for the analysis of transportation simulations (vibrations, bumps, pitch and roll)

  • Generates an automatic report, profile and charts.
  • Includes a box tool to obtain PSD breakpoints for shaker simulation. With the tools of the box it is easier and faster to obtain personalized PSDs according to:
    • PSD for three orthogonal axes for 100% CDF events.
    • PSD for three orthogonal axes for the events of the highest 20% and the lowest 80% of CDF
    • Chance PSD overlays at 80%, 90%, 95%, 99%, and 100% “at or below levels.”
    • Statistical distribution of the RMS level
  • Quick and easy setup, quick scan and batch file conversion:
    • FFT analysis, PSD, Spectrogram, Digital filtering.
    • Export data to CSV and Matlab.
