PeakVue Bearing & Gear Fault Detection
4-20 mA Loop Integration and Signal Waveform Conditioning
Engineered for field diagnostic route collection and advanced machinery troubleshooting, the CSI 2140 executes simultaneous four-channel raw waveform sampling, allowing complete cross-channel phase analysis across rotating equipment shafts. Integrated PeakVue signal processing filters out low-frequency structural vibration noise to isolate transient high-frequency stress waves generated by early-stage bearing race impacts and gearbox tooth degradation. The unit interfaces directly with 4-20 mA HART transmitters, triaxial accelerometers, and optical tachometer inputs via channel-isolated front panel connectors.
Frequently Asked Questions
Q: Can the CSI 2140 perform simultaneous four-channel acquisition without phase distortion across channels?
A: Yes, the unit utilizes synchronized analog-to-digital converters (ADCs) across all four input channels to ensure zero phase shift, allowing accurate cross-channel phase and triaxial vector analysis.
Q: How does PeakVue processing differ from standard acceleration envelope detection on the CSI 2140?
A: PeakVue samples high-frequency stress waves at peak amplitude levels without applying low-pass smoothing filters, preserving true stress-wave peak values to detect bearing and gear fatigue months before traditional spectral velocity thresholds are breached.
Field Installation Guidelines
Inspect all sensor input ports, BNC/M12 adapter interfaces, and dust covers for debris or moisture before deploying the analyzer in harsh plant environments.
Connect triaxial accelerometers or single-axis vibration sensors to channels A through D, ensuring signal cable connectors are locked firmly into position.
Align optical tachometer sensors perpendicular to reflective shaft tape at a distance of 50 mm to 300 mm for accurate shaft speed pulse tracking.
Export collected route data via Wi-Fi or high-speed USB interface to the AMS Device Manager software suite to maintain historical baseline databases.
