DC-21
Dual Channel Vibration Analyzer and Data Collector
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 band pass 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)
