Emerson CSI 2140 Machinery Health Analyzer

Frequency Analysis

• A/D converter: 24 bits of precision.
• Automatic Integrator Correction: Allows precise measurement of low frequency vibrations down to 0.2 Hz.
• Averaging modes: Normal, exponential, peak hold, order tracking, negative averaging, synchronous time
• Cursors Spectrum: Single, Harmonic, Moving Harmonic, Sideband, and Time/Frequency for waveform.
• Dynamic range: Converter has 120 dB dynamic range.
• Frequency range: DC to 10 Hz minimum, DC to 80 kHz maximum
• Frequency Units: Hz, CPM, Orders.
• Full-scale range: Accelerometer input: 0-20V, Volts input -20V + 20V
• Noise floor: Typically less than 20 μV for a 400-line spectrum at 1000 Hz maximum frequency.
• Number of averages: 5,000 in Route mode, 10,000 in Job mode.
• Resolution: 100, 200, 400, 800, 1600, 3200, 6400, or 12800 lines of resolution. True Zoom provides effective resolution of up to 300,000 lines.
• Response: Flat to DC for non-integrated and DC-coupled signals; optional AC coupling -3 dB at 1 Hz
• Scaling: Linear or Log, both X and Y
• Windows: Hanning or uniform
