The DC-21 is a fully digital, two channel, spectrum analyzer and data collector. It is intended to make:

Condition monitoring and diagnostics measurements:
  • time wave form (oscilloscope mode)
  • vibration levels in different frequency bands according to ISO standards,
    RMS, true peak, peak-peak
  • peak factor
  • autospectra
  • envelope spectra selected from multiple bandpass filters
  • rotation speed
  • amplitude and phase of rotation speed and its harmonics
  • long duration time signal recording
Rotor balancing (optional)
  • 1, 2, or 3 plane balancing
  • 8 measurement points
  • balancing using known influence coefficients without trial runs
  • utilities for calculation of trial weights,summing, and splitting weights
  • balancing at multiple operating speeds
Test diagnostics
  • RPM/amplitude/phase characteristics during machine run-up/coast down (up to 16 channels simultaneously with optional multiplexer)
  • modal analysis, resonant frequencies, logarithmic decrement (damping coefficient) for certain frequencies (optional)
  • shaft alignment shim calculation from the results of measurements with sensors or from dial indicators (optional)
